-في الـ Sass، الـ <dfn>mixin</dfn> هو مجموعة من تعريفات الـ CSS التي يمكن إعادة استخدامها في الـ stylesheet.
-
-تتطلب ميزات CSS الأحدث وقتاً قبل اعتمادها بالكامل و قبل ان تكون جاهزة للاستخدام في جميع المتصفحات. مع إضافة الميزات إلى المتصفحات، قد تحتاج قواعد CSS التي تستخدمها إلى vendor prefixes. فكّر في `box-shadow`:
+In Sass, a <dfn>mixin</dfn> is a group of CSS declarations that can be reused throughout the style sheet. The definition starts with the `@mixin` at-rule, followed by a custom name. You apply the mixin using the `@include` at-rule.
 
 ```scss
-div {
-  -webkit-box-shadow: 0px 0px 4px #fff;
-  -moz-box-shadow: 0px 0px 4px #fff;
-  -ms-box-shadow: 0px 0px 4px #fff;
-  box-shadow: 0px 0px 4px #fff;
+@mixin reset-list {
+  margin: 0;
+  padding: 0;
+  list-style: none;
+}
+
+nav ul {
+  @include reset-list;
 }
 ```
 
-يعتبر الامر الكثير من الكتابة لاعادة كتابة هذه القاعدة لجميع العناصر التي تحتوي على `box-shadow` أو لتغيير كل قيمة لاختبار تأثيرات مختلفة. يعدّ Mixins مثل الوظائف (functions) في CSS. إليك كيفية كتابة واحدة:
+Compiles to:
 
-```scss
-@mixin box-shadow($x, $y, $blur, $c){ 
-  -webkit-box-shadow: $x $y $blur $c;
-  -moz-box-shadow: $x $y $blur $c;
-  -ms-box-shadow: $x $y $blur $c;
-  box-shadow: $x $y $blur $c;
+```css
+nav ul {
+  margin: 0;
+  padding: 0;
+  list-style: none;
 }
 ```
 
-يبدأ تعريف `@mixin` يتبعه اسم مخصص. هذه الحجج ( `$x`, و `$y`, و `$blur`, و `$c` في المثال أعلاه) اختيارية. الآن في أي وقت تكون قاعدة `box-shadow` مطلوبة، خط واحد فقط يستبدل mixin الذي يضطر إلى كتابة جميع رموز (vendor prefixes). يتم استدعاء mixin مع توجيه `@include`:
+Your mixins can also take arguments, which allows their behavior to be customized. The arguments are required when using the mixin.
 
 ```scss
-div {
-  @include box-shadow(0px, 0px, 4px, #fff);
+@mixin prose($font-size, $spacing) {
+  font-size: $font-size;
+  margin: 0;
+  margin-block-end: $spacing;
+}
+
+p {
+  @include prose(1.25rem, 1rem);
+}
+
+h2 {
+  @include prose(2.4rem, 1.5rem);
+}
+```
+
+You can make arguments optional by giving the parameters default values.
+
+```scss
+@mixin text-color($color: black) {
+  color: $color;
+}
+
+p {
+  @include text-color(); /* color: black */
+}
+
+nav a {
+  @include text-color(orange);
 }
 ```
 
 # --instructions--
 
-اكتب mixin إلى `border-radius` وأعطيه حجة `$radius`. ينبغي أن تستخدم جميع الرموز (vendor prefixes) من المثال. ثم استخدم mixin باسم `border-radius` لإعطاء عنصر `#awesome` حدود نصف قطر بقيمة `15px`.
+Write a mixin named `shape` and give it 3 parameters: `$w`, `$h`, and `$bg-color`.
+
+Use the `shape` mixin to give the `#square` element a width and height of `50px`, and the color `red`. For the `#rect-a` element add a width of `100px`, a height of `50px`, and the color `blue`. Finally, for the `#rect-b` element add a width of `50px`, a height of `100px`, and the color `orange`.
 
 # --hints--
 
-يجب أن تعلن التعليمات البرمجية الخاصة بك mixin اسمه `border-radius` يحتوي على حِجَّة اسمها `$radius`.
+You should declare a mixin named `shape` with 3 parameters: `$w`, `$h`, and `$bg-color`.
 
 ```js
-assert(code.match(/@mixin\s+?border-radius\s*?\(\s*?\$radius\s*?\)\s*?{/gi));
+assert.match(code, /@mixin\s+shape\s*\(\s*\$w,\s*\$h,\s*\$bg-color\s*\)\s*{/gi);
 ```
 
-يجب أن يتضمن تعليماتك البرمجية `-webkit-border-radius` رموز (vendor prefix) التي تستخدم حِجَّة `$radius`.
+Your mixin should include a `width` property that uses the `$w` parameter.
 
 ```js
-assert(
-  __helpers.removeWhiteSpace(code).match(/-webkit-border-radius:\$radius;/gi)
-);
+assert.match(__helpers.removeWhiteSpace(code), /width:\$w;/gi);
 ```
 
-يجب أن يتضمن تعليماتك البرمجية `-moz-border-radius` رموز (vendor prefix) التي تستخدم حِجَّة `$radius`.
+Your mixin should include a `height` property that uses the `$h` parameter.
 
 ```js
-assert(
-  __helpers.removeWhiteSpace(code).match(/-moz-border-radius:\$radius;/gi)
-);
+assert.match(__helpers.removeWhiteSpace(code), /height:\$h;/gi);
 ```
 
-يجب أن يتضمن تعليماتك البرمجية `-ms-border-radius` رموز (vendor prefix) التي تستخدم حِجَّة `$radius`.
+Your mixin should include a `background-color` property that uses the `$bg-color` parameter.
 
 ```js
-assert(__helpers.removeWhiteSpace(code).match(/-ms-border-radius:\$radius;/gi));
+assert.match(__helpers.removeWhiteSpace(code), /background-color:\$bg\-color;/gi);
 ```
 
-يجب أن يتضمن تعليماتك البرمجية `border-radius` رموز (vendor prefix) التي تستخدم حِجَّة `$radius`.
+You should replace the styles inside the `#square` selector with a call to the `shape` mixin using the `@include` keyword. Setting a width and height of `50px`, and the color `red`.
 
 ```js
-assert(
-  __helpers.removeWhiteSpace(code).match(/border-radius:\$radius;/gi).length ==
-    4
-);
+assert.match(code, /#square\s*{\s*@include\s+shape\(\s*50px,\s*50px,\s*red\s*\)\s*;\s*}/gi);
 ```
 
-يجب أن تتصل التعليمات البرمجية الخاصة بك إلى `border-radius mixin` باستخدام الكلمة المفتاحية `@include`، ثم تضعها إلى `15px`.
+You should replace the styles inside the `#rect-a` selector with a call to the `shape` mixin using the `@include` keyword. Setting a width of `100px`, a height of `50px`, and the color `blue`.
 
 ```js
-assert(code.match(/@include\s+?border-radius\(\s*?15px\s*?\)\s*;/gi));

+
+# --description--
+Your game will be played against the computer. You will write a function that randomly returns `"rock"`, `"paper"` or `"scissors"`.
+
+You do not need to worry about the front-end part of the game. You will only write the logic for the game. Open the `script.js` and start following the instructions.
+
+**User stories:**
+
+1. You should have a function named `getComputerChoice`.
+
+1. Your `getComputerChoice` function should return `"rock"`, `"paper"`, or `"scissors"` at random.
+
+**Hint:** The [Math.random](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random) method returns a random number that’s greater than or equal to 0 and less than 1. Think about how you can use this to conditionally return one of the multiple choices.
+
+Your game will be played by a human player. You will write a function that takes the user's choice and returns it.
+
+1. Create a function named `getHumanChoice`.
+
+1. Write the code so that `getHumanChoice` will return one of the valid choices depending on what the user inputs.
+
+**Hint:** Use the [prompt](https://developer.mozilla.org/en-US/docs/Web/API/Window/prompt) method to get the user’s input.
+
+Your game will keep track of the player's score. You will write variables to keep track of the player's score.
+

-在 Sass 中，<dfn>mixin</dfn> 是一組 CSS 聲明，可以在整個樣式表中重複使用。
-
-CSS 的新功能需要一段時間適配後，所有瀏覽器後才能完全使用。 隨着瀏覽器的不斷升級，使用這些 CSS 規則時可能需要添加瀏覽器前綴。 考慮 `box-shadow`：
+In Sass, a <dfn>mixin</dfn> is a group of CSS declarations that can be reused throughout the style sheet. The definition starts with the `@mixin` at-rule, followed by a custom name. You apply the mixin using the `@include` at-rule.
 
 ```scss
-div {
-  -webkit-box-shadow: 0px 0px 4px #fff;
-  -moz-box-shadow: 0px 0px 4px #fff;
-  -ms-box-shadow: 0px 0px 4px #fff;
-  box-shadow: 0px 0px 4px #fff;
+@mixin reset-list {
+  margin: 0;
+  padding: 0;
+  list-style: none;
+}
+
+nav ul {
+  @include reset-list;
 }
 ```
 
-對於所有具有 `box-shadow` 屬性的元素重寫此規則，或者更改每個值以測試不同的效果，需要花費大量的精力。 Mixins 就像 CSS 的函數。 以下是一個例子：
+Compiles to:
 
-```scss
-@mixin box-shadow($x, $y, $blur, $c){ 
-  -webkit-box-shadow: $x $y $blur $c;
-  -moz-box-shadow: $x $y $blur $c;
-  -ms-box-shadow: $x $y $blur $c;
-  box-shadow: $x $y $blur $c;
+```css
+nav ul {
+  margin: 0;
+  padding: 0;
+  list-style: none;
 }
 ```
 
-定義以 `@mixin` 開頭，後跟自定義名稱。 參數（`$x`，`$y`，`$blur`，以及上例中的 `$c` ）是可選的。 現在在需要 `box-shadow` 規則的地方，只需一行 mixin 調用而無需添加所有的瀏覽器前綴。 mixin 可以通過 `@include` 指令調用。
+Your mixins can also take arguments, which allows their behavior to be customized. The arguments are required when using the mixin.
 
 ```scss
-div {
-  @include box-shadow(0px, 0px, 4px, #fff);
+@mixin prose($font-size, $spacing) {
+  font-size: $font-size;
+  margin: 0;
+  margin-block-end: $spacing;
+}
+
+p {
+  @include prose(1.25rem, 1rem);
+}
+
+h2 {
+  @include prose(2.4rem, 1.5rem);
+}
+```
+
+You can make arguments optional by giving the parameters default values.
+
+```scss
+@mixin text-color($color: black) {
+  color: $color;
+}
+
+p {
+  @include text-color(); /* color: black */
+}
+
+nav a {
+  @include text-color(orange);
 }
 ```

-爲 `border-radius` 寫一個 mixin，並給它一個 `$radius` 參數。 應該使用之前例子中的所有瀏覽器前綴。 然後使用 `border-radius` mixin 爲 `#awesome` 元素提供 `15px` 的邊框半徑。
+Write a mixin named `shape` and give it 3 parameters: `$w`, `$h`, and `$bg-color`.
+
+Use the `shape` mixin to give the `#square` element a width and height of `50px`, and the color `red`. For the `#rect-a` element add a width of `100px`, a height of `50px`, and the color `blue`. Finally, for the `#rect-b` element add a width of `50px`, a height of `100px`, and the color `orange`.
 
 # --hints--
 
-應聲明名爲 `border-radius` 的 mixin，其中包含名爲 `$radius` 的參數。
+You should declare a mixin named `shape` with 3 parameters: `$w`, `$h`, and `$bg-color`.
 
 ```js
-assert(code.match(/@mixin\s+?border-radius\s*?\(\s*?\$radius\s*?\)\s*?{/gi));
+assert.match(code, /@mixin\s+shape\s*\(\s*\$w,\s*\$h,\s*\$bg-color\s*\)\s*{/gi);
 ```
 
-應該給 `$radius` 添加 `-webkit-border-radius` 瀏覽器前綴。
+Your mixin should include a `width` property that uses the `$w` parameter.
 
 ```js
-assert(
-  __helpers.removeWhiteSpace(code).match(/-webkit-border-radius:\$radius;/gi)
-);
+assert.match(__helpers.removeWhiteSpace(code), /width:\$w;/gi);
 ```
 
-應該給 `$radius` 添加 `-moz-border-radius` 瀏覽器前綴。
+Your mixin should include a `height` property that uses the `$h` parameter.
 
 ```js
-assert(
-  __helpers.removeWhiteSpace(code).match(/-moz-border-radius:\$radius;/gi)
-);
+assert.match(__helpers.removeWhiteSpace(code), /height:\$h;/gi);
 ```
 
-應該給 `$radius` 添加 `-ms-border-radius` 瀏覽器前綴。
+Your mixin should include a `background-color` property that uses the `$bg-color` parameter.
 
 ```js
-assert(__helpers.removeWhiteSpace(code).match(/-ms-border-radius:\$radius;/gi));
+assert.match(__helpers.removeWhiteSpace(code), /background-color:\$bg\-color;/gi);
 ```
 
-應該給 `$radius` 添加 `border-radius`。
+You should replace the styles inside the `#square` selector with a call to the `shape` mixin using the `@include` keyword. Setting a width and height of `50px`, and the color `red`.
 
 ```js
-assert(
-  __helpers.removeWhiteSpace(code).match(/border-radius:\$radius;/gi).length ==
-    4
-);
+assert.match(code, /#square\s*{\s*@include\s+shape\(\s*50px,\s*50px,\s*red\s*\)\s*;\s*}/gi);
 ```
 
-應使用 `@include` 關鍵字調用 `border-radius mixin`，並將其設置爲 `15px`。
+You should replace the styles inside the `#rect-a` selector with a call to the `shape` mixin using the `@include` keyword. Setting a width of `100px`, a height of `50px`, and the color `blue`.
 
 ```js
-assert(code.match(/@include\s+?border-radius\(\s*?15px\s*?\)\s*;/gi));
+assert.match(code, /#rect-a\s*{\s*@include\s+shape\(\s*100px,\s*50px,\s*blue\s*\)\s*;\s*}/gi);

+
+# --description--
+Your game will be played against the computer. You will write a function that randomly returns `"rock"`, `"paper"` or `"scissors"`.
+
+You do not need to worry about the front-end part of the game. You will only write the logic for the game. Open the `script.js` and start following the instructions.
+
+**User stories:**
+
+1. You should have a function named `getComputerChoice`.
+
+1. Your `getComputerChoice` function should return `"rock"`, `"paper"`, or `"scissors"` at random.
+
+**Hint:** The [Math.random](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random) method returns a random number that’s greater than or equal to 0 and less than 1. Think about how you can use this to conditionally return one of the multiple choices.
+
+Your game will be played by a human player. You will write a function that takes the user's choice and returns it.
+
+1. Create a function named `getHumanChoice`.
+
+1. Write the code so that `getHumanChoice` will return one of the valid choices depending on what the user inputs.
+
+**Hint:** Use the [prompt](https://developer.mozilla.org/en-US/docs/Web/API/Window/prompt) method to get the user’s input.
+
+Your game will keep track of the player's score. You will write variables to keep track of the player's score.
+
+1. Create two new variables named `humanScore` and `computerScore` in the global scope.
+
+1. Initialize those variables with the value of `0`.
+
+Your game will be played round by round. You will write a function that takes the human and computer player choices as arguments, plays a single round, increments the round winner’s score and logs a winner announcement.
+
+1. Create a new function named `playRound`.
+
+1. Define two parameters for `playRound`. Parameter one `humanChoice` and parameter two `computerChoice`. Use these two parameters to take the human and computer choices as arguments.
+
+1. Make your function’s `humanChoice` parameter case-insensitive so that players can input `"rock"`, `"ROCK"`, `"RocK"`, or other variations.
+
+1. Write the code for your `playRound` function that returns a string value representing the round winner.
+
+- If it is a tie, it should return `"It's a tie!"`.
+
+- If the player wins, it should return `"You win! [player choice] beats [computer choice]"`.
+
+- If the computer wins, it should return `"You lose! [computer choice] beats [player choice]"`.
+
+1. Increment the `humanScore` or `computerScore` variable based on the round winner.
+
+Your game will play 3 rounds. You will write a function named `playGame` that calls `playRound` to play 3 rounds, keeps track of the scores, and declares a winner at the end.
+
+1. Create a new function named `playGame`.
+
+1. Create a loop that plays 3 rounds and calls the `playRound` function each time with the human's choice and the computer's choice functions as arguments.
+
+1. At the end of the game, return the winner of the game based on who won the most rounds.
+
+- If the human player wins more rounds than the computer player, return a message that says `"You win the game!"`.
+
+- If the computer player wins more rounds than the human player, return a message that says `"You lose the game!"`.

+```
+
+Your `playRound` function should return the string `"It's a tie!"` if the human and computer choices are the same.
+
+```js
+assert.equal(playRound("rock", "rock"), "It's a tie!");

+
+```js
+assert.equal(playRound("rock", "paper"), "You lose! paper beats rock");
+```
+
+Your `playRound` function should increment the `humanScore` or `computerScore` variable based on the round winner.

-在 Sass 中，<dfn>mixin</dfn> 是一组 CSS 声明，可以在整个样式表中重复使用。
-
-CSS 的新功能需要一段时间适配后，所有浏览器后才能完全使用。 随着浏览器的不断升级，使用这些 CSS 规则时可能需要添加浏览器前缀。 考虑 `box-shadow`：
+In Sass, a <dfn>mixin</dfn> is a group of CSS declarations that can be reused throughout the style sheet. The definition starts with the `@mixin` at-rule, followed by a custom name. You apply the mixin using the `@include` at-rule.
 
 ```scss
-div {
-  -webkit-box-shadow: 0px 0px 4px #fff;
-  -moz-box-shadow: 0px 0px 4px #fff;
-  -ms-box-shadow: 0px 0px 4px #fff;
-  box-shadow: 0px 0px 4px #fff;
+@mixin reset-list {
+  margin: 0;
+  padding: 0;
+  list-style: none;
+}
+
+nav ul {
+  @include reset-list;
 }
 ```
 
-对于所有具有 `box-shadow` 属性的元素重写此规则，或者更改每个值以测试不同的效果，需要花费大量的精力。 Mixins 就像 CSS 的函数。 以下是一个例子：
+Compiles to:
 
-```scss
-@mixin box-shadow($x, $y, $blur, $c){ 
-  -webkit-box-shadow: $x $y $blur $c;
-  -moz-box-shadow: $x $y $blur $c;
-  -ms-box-shadow: $x $y $blur $c;
-  box-shadow: $x $y $blur $c;
+```css
+nav ul {
+  margin: 0;
+  padding: 0;
+  list-style: none;
 }
 ```
 
-定义以 `@mixin` 开头，后跟自定义名称。 参数（`$x`，`$y`，`$blur`，以及上例中的 `$c` ）是可选的。 现在在需要 `box-shadow` 规则的地方，只需一行 mixin 调用而无需添加所有的浏览器前缀。 mixin 可以通过 `@include` 指令调用。
+Your mixins can also take arguments, which allows their behavior to be customized. The arguments are required when using the mixin.
 
 ```scss
-div {
-  @include box-shadow(0px, 0px, 4px, #fff);
+@mixin prose($font-size, $spacing) {
+  font-size: $font-size;
+  margin: 0;
+  margin-block-end: $spacing;
+}
+
+p {
+  @include prose(1.25rem, 1rem);
+}
+
+h2 {
+  @include prose(2.4rem, 1.5rem);
+}
+```
+
+You can make arguments optional by giving the parameters default values.
+
+```scss
+@mixin text-color($color: black) {
+  color: $color;
+}
+
+p {
+  @include text-color(); /* color: black */
+}
+
+nav a {
+  @include text-color(orange);
 }
 ```

-为 `border-radius` 写一个 mixin，并给它一个 `$radius` 参数。 应该使用之前例子中的所有浏览器前缀。 然后使用 `border-radius` mixin 为 `#awesome` 元素提供 `15px` 的边框半径。
+Write a mixin named `shape` and give it 3 parameters: `$w`, `$h`, and `$bg-color`.
+
+Use the `shape` mixin to give the `#square` element a width and height of `50px`, and the color `red`. For the `#rect-a` element add a width of `100px`, a height of `50px`, and the color `blue`. Finally, for the `#rect-b` element add a width of `50px`, a height of `100px`, and the color `orange`.
 
 # --hints--
 
-应声明名为 `border-radius` 的 mixin，其中包含名为 `$radius` 的参数。
+You should declare a mixin named `shape` with 3 parameters: `$w`, `$h`, and `$bg-color`.
 
 ```js
-assert(code.match(/@mixin\s+?border-radius\s*?\(\s*?\$radius\s*?\)\s*?{/gi));
+assert.match(code, /@mixin\s+shape\s*\(\s*\$w,\s*\$h,\s*\$bg-color\s*\)\s*{/gi);
 ```
 
-应该给 `$radius` 添加 `-webkit-border-radius` 浏览器前缀。
+Your mixin should include a `width` property that uses the `$w` parameter.
 
 ```js
-assert(
-  __helpers.removeWhiteSpace(code).match(/-webkit-border-radius:\$radius;/gi)
-);
+assert.match(__helpers.removeWhiteSpace(code), /width:\$w;/gi);
 ```
 
-应该给 `$radius` 添加 `-moz-border-radius` 浏览器前缀。
+Your mixin should include a `height` property that uses the `$h` parameter.
 
 ```js
-assert(
-  __helpers.removeWhiteSpace(code).match(/-moz-border-radius:\$radius;/gi)
-);
+assert.match(__helpers.removeWhiteSpace(code), /height:\$h;/gi);
 ```
 
-应该给 `$radius` 添加 `-ms-border-radius` 浏览器前缀。
+Your mixin should include a `background-color` property that uses the `$bg-color` parameter.
 
 ```js
-assert(__helpers.removeWhiteSpace(code).match(/-ms-border-radius:\$radius;/gi));
+assert.match(__helpers.removeWhiteSpace(code), /background-color:\$bg\-color;/gi);
 ```
 
-应该给 `$radius` 添加 `border-radius`。
+You should replace the styles inside the `#square` selector with a call to the `shape` mixin using the `@include` keyword. Setting a width and height of `50px`, and the color `red`.
 
 ```js
-assert(
-  __helpers.removeWhiteSpace(code).match(/border-radius:\$radius;/gi).length ==
-    4
-);
+assert.match(code, /#square\s*{\s*@include\s+shape\(\s*50px,\s*50px,\s*red\s*\)\s*;\s*}/gi);
 ```
 
-应使用 `@include` 关键字调用 `border-radius mixin`，并将其设置为 `15px`。
+You should replace the styles inside the `#rect-a` selector with a call to the `shape` mixin using the `@include` keyword. Setting a width of `100px`, a height of `50px`, and the color `blue`.
 
 ```js
-assert(code.match(/@include\s+?border-radius\(\s*?15px\s*?\)\s*;/gi));

+# --description--
+Your game will be played against the computer. You will write a function that randomly returns `"rock"`, `"paper"` or `"scissors"`.
+
+You do not need to worry about the front-end part of the game. You will only write the logic for the game. Open the `script.js` and start following the instructions.
+
+**User stories:**
+
+1. You should have a function named `getComputerChoice`.
+
+1. Your `getComputerChoice` function should return `"rock"`, `"paper"`, or `"scissors"` at random.
+
+**Hint:** The [Math.random](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random) method returns a random number that’s greater than or equal to 0 and less than 1. Think about how you can use this to conditionally return one of the multiple choices.
+
+Your game will be played by a human player. You will write a function that takes the user's choice and returns it.
+
+1. Create a function named `getHumanChoice`.
+
+1. Write the code so that `getHumanChoice` will return one of the valid choices depending on what the user inputs.
+
+**Hint:** Use the [prompt](https://developer.mozilla.org/en-US/docs/Web/API/Window/prompt) method to get the user’s input.
+
+Your game will keep track of the player's score. You will write variables to keep track of the player's score.
+
+1. Create two new variables named `humanScore` and `computerScore` in the global scope.
+
+1. Initialize those variables with the value of `0`.
+
+Your game will be played round by round. You will write a function that takes the human and computer player choices as arguments, plays a single round, increments the round winner’s score and logs a winner announcement.
+
+1. Create a new function named `playRound`.
+
+1. Define two parameters for `playRound`. Parameter one `humanChoice` and parameter two `computerChoice`. Use these two parameters to take the human and computer choices as arguments.
+
+1. Make your function’s `humanChoice` parameter case-insensitive so that players can input `"rock"`, `"ROCK"`, `"RocK"`, or other variations.
+
+1. Write the code for your `playRound` function that returns a string value representing the round winner.
+
+- If it is a tie, it should return `"It's a tie!"`.
+
+- If the player wins, it should return `"You win! [player choice] beats [computer choice]"`.
+
+- If the computer wins, it should return `"You lose! [computer choice] beats [player choice]"`.
+
+1. Increment the `humanScore` or `computerScore` variable based on the round winner.
+
+Your game will play 3 rounds. You will write a function named `playGame` that calls `playRound` to play 3 rounds, keeps track of the scores, and declares a winner at the end.
+
+1. Create a new function named `playGame`.
+
+1. Create a loop that plays 3 rounds and calls the `playRound` function each time with the human's choice and the computer's choice functions as arguments.
+
+1. At the end of the game, return the winner of the game based on who won the most rounds.
+
+- If the human player wins more rounds than the computer player, return a message that says `"You win the game!"`.
+
+- If the computer player wins more rounds than the human player, return a message that says `"You lose the game!"`.

-En Sass, un <dfn>mixin</dfn> es un grupo de declaraciones de CSS que pueden reutilizarse a través de la hoja de estilo.
-
-Las nuevas funciones de CSS tardan en ser adoptadas por completo y estar listas para su uso en todos los navegadores. A medida que se agregan funciones a los navegadores, las reglas CSS que las utilizan pueden necesitar prefijos de proveedor. Consideremos `box-shadow`:
+In Sass, a <dfn>mixin</dfn> is a group of CSS declarations that can be reused throughout the style sheet. The definition starts with the `@mixin` at-rule, followed by a custom name. You apply the mixin using the `@include` at-rule.
 
 ```scss
-div {
-  -webkit-box-shadow: 0px 0px 4px #fff;
-  -moz-box-shadow: 0px 0px 4px #fff;
-  -ms-box-shadow: 0px 0px 4px #fff;
-  box-shadow: 0px 0px 4px #fff;
+@mixin reset-list {
+  margin: 0;
+  padding: 0;
+  list-style: none;
+}
+
+nav ul {
+  @include reset-list;
 }
 ```
 
-Es mucho teclear para reescribir esta regla para todos los elementos que tienen un `box-shadow`, o para cambiar cada valor para probar diferentes efectos. Mixins son como funciones para CSS. Aquí está cómo escribir una:
+Compiles to:
 
-```scss
-@mixin box-shadow($x, $y, $blur, $c){ 
-  -webkit-box-shadow: $x $y $blur $c;
-  -moz-box-shadow: $x $y $blur $c;
-  -ms-box-shadow: $x $y $blur $c;
-  box-shadow: $x $y $blur $c;
+```css
+nav ul {
+  margin: 0;
+  padding: 0;
+  list-style: none;
 }
 ```
 
-La definición empieza con `@mixin` seguido de un nombre personalizado. Los parámetros ( `$x`, `$y`, `$blur`, y `$c` en el ejemplo anterior) son opcionales. Ahora cada vez que se necesite una regla `box-shadow`, una sola línea llamando al mixin reemplaza el tener que escribir todos los prefijos del proveedor. Se llama a un mixin con la directiva `@include`:
+Your mixins can also take arguments, which allows their behavior to be customized. The arguments are required when using the mixin.
 
 ```scss
-div {
-  @include box-shadow(0px, 0px, 4px, #fff);
+@mixin prose($font-size, $spacing) {
+  font-size: $font-size;
+  margin: 0;
+  margin-block-end: $spacing;
+}
+
+p {
+  @include prose(1.25rem, 1rem);
+}
+
+h2 {
+  @include prose(2.4rem, 1.5rem);
+}
+```
+
+You can make arguments optional by giving the parameters default values.
+
+```scss
+@mixin text-color($color: black) {
+  color: $color;
+}
+
+p {
+  @include text-color(); /* color: black */
+}
+
+nav a {
+  @include text-color(orange);
 }
 ```
 
 # --instructions--
 
-Escribe un mixin para `border-radius` y dale un parámetro `$radius`. Debe utilizar todos los prefijos de proveedor del ejemplo. Luego usa el mixin `border-radius` para dar al elemento `#awesome` un border radius de `15px`.
+Write a mixin named `shape` and give it 3 parameters: `$w`, `$h`, and `$bg-color`.
+
+Use the `shape` mixin to give the `#square` element a width and height of `50px`, and the color `red`. For the `#rect-a` element add a width of `100px`, a height of `50px`, and the color `blue`. Finally, for the `#rect-b` element add a width of `50px`, a height of `100px`, and the color `orange`.

+# --description--
+Your game will be played against the computer. You will write a function that randomly returns `"rock"`, `"paper"` or `"scissors"`.
+
+You do not need to worry about the front-end part of the game. You will only write the logic for the game. Open the `script.js` and start following the instructions.
+
+**User stories:**
+
+1. You should have a function named `getComputerChoice`.
+
+1. Your `getComputerChoice` function should return `"rock"`, `"paper"`, or `"scissors"` at random.
+
+**Hint:** The [Math.random](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random) method returns a random number that’s greater than or equal to 0 and less than 1. Think about how you can use this to conditionally return one of the multiple choices.
+
+Your game will be played by a human player. You will write a function that takes the user's choice and returns it.
+
+1. Create a function named `getHumanChoice`.
+
+1. Write the code so that `getHumanChoice` will return one of the valid choices depending on what the user inputs.
+
+**Hint:** Use the [prompt](https://developer.mozilla.org/en-US/docs/Web/API/Window/prompt) method to get the user’s input.
+
+Your game will keep track of the player's score. You will write variables to keep track of the player's score.
+
+1. Create two new variables named `humanScore` and `computerScore` in the global scope.
+
+1. Initialize those variables with the value of `0`.
+
+Your game will be played round by round. You will write a function that takes the human and computer player choices as arguments, plays a single round, increments the round winner’s score and logs a winner announcement.
+
+1. Create a new function named `playRound`.
+
+1. Define two parameters for `playRound`. Parameter one `humanChoice` and parameter two `computerChoice`. Use these two parameters to take the human and computer choices as arguments.
+
+1. Make your function’s `humanChoice` parameter case-insensitive so that players can input `"rock"`, `"ROCK"`, `"RocK"`, or other variations.
+
+1. Write the code for your `playRound` function that returns a string value representing the round winner.
+
+- If it is a tie, it should return `"It's a tie!"`.
+
+- If the player wins, it should return `"You win! [player choice] beats [computer choice]"`.
+
+- If the computer wins, it should return `"You lose! [computer choice] beats [player choice]"`.
+
+1. Increment the `humanScore` or `computerScore` variable based on the round winner.
+
+Your game will play 3 rounds. You will write a function named `playGame` that calls `playRound` to play 3 rounds, keeps track of the scores, and declares a winner at the end.
+
+1. Create a new function named `playGame`.
+
+1. Create a loop that plays 3 rounds and calls the `playRound` function each time with the human's choice and the computer's choice functions as arguments.
+
+1. At the end of the game, return the winner of the game based on who won the most rounds.
+
+- If the human player wins more rounds than the computer player, return a message that says `"You win the game!"`.
+
+- If the computer player wins more rounds than the human player, return a message that says `"You lose the game!"`.
+
+# --hints--
+
+You should have a function called `getComputerChoice`
+
+```js
+assert.isFunction(getComputerChoice);
+```
+
+Your `getComputerChoice` function should return `"rock"`, `"paper"`, or `"scissors"` at random.
+
+```js
+const counts = {}
+for (let i = 0; i < 100; i++) {
+  const result = getComputerChoice();
+  counts[result] = (counts[result] ?? 0) + 1;
+}
+assert.lengthOf(Object.keys(counts), 3);
+assert.include(Object.keys(counts), "rock");
+assert.include(Object.keys(counts), "paper"); 
+assert.include(Object.keys(counts), "scissors");
+```
+
+You should have a function called `getHumanChoice`
+
+```js
+assert.isFunction(getHumanChoice);
+```
+
+You should have two variables named `humanScore` and `computerScore` in the global scope.
+
+```js
+assert.exists(humanScore);
+assert.exists(computerScore);
+```
+
+You should have a function called `playRound`
+
+```js
+assert.isFunction(playRound);
+```
+
+Your `playRound` function should take the human and computer player choices as arguments with the parameters `humanChoice` and `computerChoice`.
+
+```js
+assert.match(playRound.toString(), /\s*(?:\bhumanChoice\b\s*,\s*\bcomputerChoice\b)/);
+```
+
+Your `playRound` function should be case-insensitive so that players can input `"rock"`, `"ROCK"`, `"RocK"`, or other variations.
+
+```js
+assert.match(playRound.toString(), /\bhumanChoice\s*\.toLowerCase\(\)/);
+```
+
+Your `playRound` function should return the string `"It's a tie!"` if the human and computer choices are the same.
+
+```js
+assert.equal(playRound("rock", "rock"), "It's a tie!");
+```
+
+Your `playRound` function should return the string `"You win! [player choice] beats [computer choice]"` if the player wins.
+
+```js
+assert.equal(playRound("rock", "scissors"), "You win! rock beats scissors");
+```
+
+Your `playRound` function should return the string `"You lose! [computer choice] beats [player choice]"` if the computer wins.
+
+```js
+assert.equal(playRound("rock", "paper"), "You lose! paper beats rock");
+```
+
+Your `playRound` function should increment the `humanScore` or `computerScore` variable based on the round winner.
+
+```js
+humanScore = 0;
+computerScore = 0;
+playRound("rock", "scissors");
+assert.equal(humanScore, 1);
+```
+
+You should have a function called `playGame`.
+
+```js
+assert.isFunction(playGame);
+```
+
+You should use a loop to play 3 rounds.
+
+```js
+assert.match(playGame.toString(), /\bfor\s*\(/);
+```
+
+You should return the winner of the game based on who won the most rounds.
+
+```js
+window.prompt = () => "rock";
+assert.match(playGame(), /You (win|lose) the game!/);
+```

-In Sass ist ein <dfn>Mixin</dfn> eine Gruppe von CSS-Deklarationen, die im gesamten Stylesheet wiederverwendet werden können.
-
-Neuere CSS-Funktionen brauchen Zeit, bis sie vollständig übernommen werden und in allen Browsern einsatzbereit sind. Wenn neue Funktionen zu den Browsern hinzugefügt werden, benötigen CSS-Regeln, die diese nutzen, möglicherweise Herstellerpräfixe. Schau dir `box-shadow` an:
+In Sass, a <dfn>mixin</dfn> is a group of CSS declarations that can be reused throughout the style sheet. The definition starts with the `@mixin` at-rule, followed by a custom name. You apply the mixin using the `@include` at-rule.
 
 ```scss
-div {
-  -webkit-box-shadow: 0px 0px 4px #fff;
-  -moz-box-shadow: 0px 0px 4px #fff;
-  -ms-box-shadow: 0px 0px 4px #fff;
-  box-shadow: 0px 0px 4px #fff;
+@mixin reset-list {
+  margin: 0;
+  padding: 0;
+  list-style: none;
+}
+
+nav ul {
+  @include reset-list;
 }
 ```
 
-Es ist eine Menge Tipparbeit, diese Regel für alle Elemente, die einen `box-shadow` haben, neu zu schreiben oder jeden Wert zu ändern, um verschiedene Effekte zu testen. Mixins sind wie Funktionen für CSS. Hier erfährst du, wie du eines schreiben kannst:
+Compiles to:
 
-```scss
-@mixin box-shadow($x, $y, $blur, $c){ 
-  -webkit-box-shadow: $x $y $blur $c;
-  -moz-box-shadow: $x $y $blur $c;
-  -ms-box-shadow: $x $y $blur $c;
-  box-shadow: $x $y $blur $c;
+```css
+nav ul {
+  margin: 0;
+  padding: 0;
+  list-style: none;
 }
 ```
 
-Die Definition beginnt mit `@mixin`, gefolgt von einem eigenen Namen. Die Parameter (`$x`, `$y`, `$blur` und `$c` im obigen Beispiel) sind optional. Jedes Mal, wenn eine `box-shadow`-Regel benötigt wird, reicht jetzt eine einzige Zeile, die das Mixin aufruft, um alle Präfixe der Hersteller zu ersetzen. Ein Mixin wird mit der `@include` Direktive aufgerufen:
+Your mixins can also take arguments, which allows their behavior to be customized. The arguments are required when using the mixin.
 
 ```scss
-div {
-  @include box-shadow(0px, 0px, 4px, #fff);
+@mixin prose($font-size, $spacing) {
+  font-size: $font-size;
+  margin: 0;
+  margin-block-end: $spacing;
+}
+
+p {
+  @include prose(1.25rem, 1rem);
+}
+
+h2 {
+  @include prose(2.4rem, 1.5rem);
+}
+```
+
+You can make arguments optional by giving the parameters default values.
+
+```scss
+@mixin text-color($color: black) {
+  color: $color;
+}
+
+p {
+  @include text-color(); /* color: black */
+}
+
+nav a {
+  @include text-color(orange);
 }
 ```
 
 # --instructions--
 
-Schreibe ein Mixin für `border-radius` und gib ihm einen Parameter `$radius`. Es sollte alle Anbieter-Präfixe aus dem Beispiel verwenden. Dann benutze das Mixin `border-radius`, um dem Element `#awesome` einen border-radius von `15px` zu geben.
+Write a mixin named `shape` and give it 3 parameters: `$w`, `$h`, and `$bg-color`.
+
+Use the `shape` mixin to give the `#square` element a width and height of `50px`, and the color `red`. For the `#rect-a` element add a width of `100px`, a height of `50px`, and the color `blue`. Finally, for the `#rect-b` element add a width of `50px`, a height of `100px`, and the color `orange`.

 Hex-Farbwerte beginnen mit einem `#`-Zeichen und enden mit sechs Zeichen in Form von 0-9 und A-F. Das erste Zeichenpaar repräsentiert rot, das zweite Paar grün und das dritte blau. Zum Beispiel: `#4B5320`.

+# --description--
+Your game will be played against the computer. You will write a function that randomly returns `"rock"`, `"paper"` or `"scissors"`.
+
+You do not need to worry about the front-end part of the game. You will only write the logic for the game. Open the `script.js` and start following the instructions.
+
+**User stories:**
+
+1. You should have a function named `getComputerChoice`.
+
+1. Your `getComputerChoice` function should return `"rock"`, `"paper"`, or `"scissors"` at random.
+
+**Hint:** The [Math.random](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random) method returns a random number that’s greater than or equal to 0 and less than 1. Think about how you can use this to conditionally return one of the multiple choices.
+
+Your game will be played by a human player. You will write a function that takes the user's choice and returns it.
+
+1. Create a function named `getHumanChoice`.
+
+1. Write the code so that `getHumanChoice` will return one of the valid choices depending on what the user inputs.
+
+**Hint:** Use the [prompt](https://developer.mozilla.org/en-US/docs/Web/API/Window/prompt) method to get the user’s input.
+
+Your game will keep track of the player's score. You will write variables to keep track of the player's score.
+
+1. Create two new variables named `humanScore` and `computerScore` in the global scope.
+
+1. Initialize those variables with the value of `0`.
+
+Your game will be played round by round. You will write a function that takes the human and computer player choices as arguments, plays a single round, increments the round winner’s score and logs a winner announcement.
+
+1. Create a new function named `playRound`.

-In Sass, un <dfn>mixin</dfn> è un gruppo di dichiarazioni CSS che possono essere riutilizzate in tutto il foglio di stile.
-
-Ci vuole tempo prima che le nuove funzionalità di CSS siano completamente adottate e utilizzabili in tutti i browser. Poiché le funzionalità vengono inizialmente aggiunte ai singoli browser, le regole CSS che le utilizzano potrebbero avere bisogno di prefissi del fornitore. Considera `box-shadow`:
+In Sass, a <dfn>mixin</dfn> is a group of CSS declarations that can be reused throughout the style sheet. The definition starts with the `@mixin` at-rule, followed by a custom name. You apply the mixin using the `@include` at-rule.
 
 ```scss
-div {
-  -webkit-box-shadow: 0px 0px 4px #fff;
-  -moz-box-shadow: 0px 0px 4px #fff;
-  -ms-box-shadow: 0px 0px 4px #fff;
-  box-shadow: 0px 0px 4px #fff;
+@mixin reset-list {
+  margin: 0;
+  padding: 0;
+  list-style: none;
+}
+
+nav ul {
+  @include reset-list;
 }
 ```
 
-Ci sarebbe molto da digitare per riscrivere questa regola per tutti gli elementi che hanno una `box-shadow`, o per modificare ogni valore per testare effetti differenti. I mixin sono come funzioni per il CSS. Ecco come scriverne uno:
+Compiles to:
 
-```scss
-@mixin box-shadow($x, $y, $blur, $c){ 
-  -webkit-box-shadow: $x $y $blur $c;
-  -moz-box-shadow: $x $y $blur $c;
-  -ms-box-shadow: $x $y $blur $c;
-  box-shadow: $x $y $blur $c;
+```css
+nav ul {
+  margin: 0;
+  padding: 0;
+  list-style: none;
 }
 ```
 
-La definizione inizia con `@mixin` seguito da un nome personalizzato. I parametri ( `$x`, `$y`, `$blur`e `$c` nell'esempio sopra) sono opzionali. Ora ogni volta che è necessaria una regola `box-shadow`, invece di dover digitare tutti i prefissi dei venditori dovremo scrivere una singola linea che chiama il mixin. Un mixin è chiamato con la direttiva `@include`:
+Your mixins can also take arguments, which allows their behavior to be customized. The arguments are required when using the mixin.
 
 ```scss
-div {
-  @include box-shadow(0px, 0px, 4px, #fff);
+@mixin prose($font-size, $spacing) {
+  font-size: $font-size;
+  margin: 0;
+  margin-block-end: $spacing;
+}
+
+p {
+  @include prose(1.25rem, 1rem);
+}
+
+h2 {
+  @include prose(2.4rem, 1.5rem);
+}
+```
+
+You can make arguments optional by giving the parameters default values.
+
+```scss
+@mixin text-color($color: black) {
+  color: $color;
+}
+
+p {
+  @include text-color(); /* color: black */
+}
+
+nav a {
+  @include text-color(orange);
 }
 ```
 
 # --instructions--
 
-Scrivi un mixin per `border-radius` e dagli un parametro `$radius`. Dovrebbe usare tutti i prefissi del fornitore dell'esempio. Quindi usa il mixin `border-radius` per dare all'elemento `#awesome` un raggio di curvatura di `15px`.
+Write a mixin named `shape` and give it 3 parameters: `$w`, `$h`, and `$bg-color`.
+
+Use the `shape` mixin to give the `#square` element a width and height of `50px`, and the color `red`. For the `#rect-a` element add a width of `100px`, a height of `50px`, and the color `blue`. Finally, for the `#rect-b` element add a width of `50px`, a height of `100px`, and the color `orange`.
 
 # --hints--
 
-Il tuo codice dovrebbe dichiarare un mixin chiamato `border-radius` che ha un parametro denominato `$radius`.
+You should declare a mixin named `shape` with 3 parameters: `$w`, `$h`, and `$bg-color`.
 
 ```js
-assert(code.match(/@mixin\s+?border-radius\s*?\(\s*?\$radius\s*?\)\s*?{/gi));
+assert.match(code, /@mixin\s+shape\s*\(\s*\$w,\s*\$h,\s*\$bg-color\s*\)\s*{/gi);
 ```
 
-Il tuo codice dovrebbe includere il prefisso del fornitore `-webkit-border-radius` che utilizza il parametro `$radius`.
+Your mixin should include a `width` property that uses the `$w` parameter.
 
 ```js
-assert(
-  __helpers.removeWhiteSpace(code).match(/-webkit-border-radius:\$radius;/gi)
-);
+assert.match(__helpers.removeWhiteSpace(code), /width:\$w;/gi);
 ```
 
-Il tuo codice dovrebbe includere il prefisso del fornitore `-moz-border-radius` che utilizza il parametro `$radius`.
+Your mixin should include a `height` property that uses the `$h` parameter.
 
 ```js
-assert(
-  __helpers.removeWhiteSpace(code).match(/-moz-border-radius:\$radius;/gi)
-);
+assert.match(__helpers.removeWhiteSpace(code), /height:\$h;/gi);
 ```
 
-Il tuo codice dovrebbe includere il prefisso del fornitore `-ms-border-radius` che utilizza il parametro `$radius`.
+Your mixin should include a `background-color` property that uses the `$bg-color` parameter.

-Il tuo codice dovrebbe includere la regola generale `border-radius` che utilizza il parametro `$radius`.
+You should replace the styles inside the `#square` selector with a call to the `shape` mixin using the `@include` keyword. Setting a width and height of `50px`, and the color `red`.

+
+# --description--
+Your game will be played against the computer. You will write a function that randomly returns `"rock"`, `"paper"` or `"scissors"`.
+
+You do not need to worry about the front-end part of the game. You will only write the logic for the game. Open the `script.js` and start following the instructions.
+
+**User stories:**
+
+1. You should have a function named `getComputerChoice`.
+
+1. Your `getComputerChoice` function should return `"rock"`, `"paper"`, or `"scissors"` at random.
+
+**Hint:** The [Math.random](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random) method returns a random number that’s greater than or equal to 0 and less than 1. Think about how you can use this to conditionally return one of the multiple choices.
+
+Your game will be played by a human player. You will write a function that takes the user's choice and returns it.
+
+1. Create a function named `getHumanChoice`.
+
+1. Write the code so that `getHumanChoice` will return one of the valid choices depending on what the user inputs.
+
+**Hint:** Use the [prompt](https://developer.mozilla.org/en-US/docs/Web/API/Window/prompt) method to get the user’s input.
+
+Your game will keep track of the player's score. You will write variables to keep track of the player's score.
+
+1. Create two new variables named `humanScore` and `computerScore` in the global scope.
+
+1. Initialize those variables with the value of `0`.
+
+Your game will be played round by round. You will write a function that takes the human and computer player choices as arguments, plays a single round, increments the round winner’s score and logs a winner announcement.
+
+1. Create a new function named `playRound`.
+
+1. Define two parameters for `playRound`. Parameter one `humanChoice` and parameter two `computerChoice`. Use these two parameters to take the human and computer choices as arguments.
+
+1. Make your function’s `humanChoice` parameter case-insensitive so that players can input `"rock"`, `"ROCK"`, `"RocK"`, or other variations.
+
+1. Write the code for your `playRound` function that returns a string value representing the round winner.
+
+- If it is a tie, it should return `"It's a tie!"`.
+
+- If the player wins, it should return `"You win! [player choice] beats [computer choice]"`.
+
+- If the computer wins, it should return `"You lose! [computer choice] beats [player choice]"`.
+
+1. Increment the `humanScore` or `computerScore` variable based on the round winner.
+
+Your game will play 3 rounds. You will write a function named `playGame` that calls `playRound` to play 3 rounds, keeps track of the scores, and declares a winner at the end.
+
+1. Create a new function named `playGame`.
+
+1. Create a loop that plays 3 rounds and calls the `playRound` function each time with the human's choice and the computer's choice functions as arguments.
+
+1. At the end of the game, return the winner of the game based on who won the most rounds.
+
+- If the human player wins more rounds than the computer player, return a message that says `"You win the game!"`.
+
+- If the computer player wins more rounds than the human player, return a message that says `"You lose the game!"`.

+```
+
+Your `playRound` function should return the string `"It's a tie!"` if the human and computer choices are the same.
+
+```js
+assert.equal(playRound("rock", "rock"), "It's a tie!");
+```
+
+Your `playRound` function should return the string `"You win! [player choice] beats [computer choice]"` if the player wins.

+Your `playRound` function should return the string `"You lose! [computer choice] beats [player choice]"` if the computer wins.
+
+```js
+assert.equal(playRound("rock", "paper"), "You lose! paper beats rock");

-Sass の<dfn>ミックスイン</dfn>は、スタイルシート全体で再利用できる CSS 宣言のグループです。
-
-新しい CSS 機能ほど、完全に採用されてすべてのブラウザーで使用できるようになるまでに時間がかかります。 機能がブラウザーに追加されるまでの間、それらの機能を使用している CSS ルールではベンダープレフィックスが必要になる場合があります。 たとえば `box-shadow` を考えてみましょう。
+In Sass, a <dfn>mixin</dfn> is a group of CSS declarations that can be reused throughout the style sheet. The definition starts with the `@mixin` at-rule, followed by a custom name. You apply the mixin using the `@include` at-rule.
 
 ```scss
-div {
-  -webkit-box-shadow: 0px 0px 4px #fff;
-  -moz-box-shadow: 0px 0px 4px #fff;
-  -ms-box-shadow: 0px 0px 4px #fff;
-  box-shadow: 0px 0px 4px #fff;
+@mixin reset-list {
+  margin: 0;
+  padding: 0;
+  list-style: none;
+}
+
+nav ul {
+  @include reset-list;
 }
 ```
 
-`box-shadow` のあるすべての要素でこのルールを書き直したり、それぞれの値を変えてさまざまな効果をテストしたりするには、たくさんの入力が必要になります。 ミックスインは CSS 版の関数のようなもので、 次のように記述します。
+Compiles to:
 
-```scss
-@mixin box-shadow($x, $y, $blur, $c){ 
-  -webkit-box-shadow: $x $y $blur $c;
-  -moz-box-shadow: $x $y $blur $c;
-  -ms-box-shadow: $x $y $blur $c;
-  box-shadow: $x $y $blur $c;
+```css
+nav ul {
+  margin: 0;
+  padding: 0;
+  list-style: none;
 }
 ```
 
-定義は `@mixin` で始まり、その後にカスタム名を付けます。 パラメーター (前の例では `$x`、`$y`、`$blur`、`$c`) は任意です。 これで、`box-shadow` ルールが必要になったときはいつでも、ミックスインを呼び出す 1 行だけで済み、すべてのベンダープレフィックスを入力する必要がなくなります。 ミックスインは `@include` ディレクティブを使用して呼び出します。
+Your mixins can also take arguments, which allows their behavior to be customized. The arguments are required when using the mixin.
 
 ```scss
-div {
-  @include box-shadow(0px, 0px, 4px, #fff);
+@mixin prose($font-size, $spacing) {
+  font-size: $font-size;
+  margin: 0;
+  margin-block-end: $spacing;
+}
+
+p {
+  @include prose(1.25rem, 1rem);
+}
+
+h2 {
+  @include prose(2.4rem, 1.5rem);
+}
+```
+
+You can make arguments optional by giving the parameters default values.
+
+```scss
+@mixin text-color($color: black) {
+  color: $color;
+}
+
+p {
+  @include text-color(); /* color: black */
+}
+
+nav a {
+  @include text-color(orange);
 }
 ```
 
 # --instructions--
 
-`border-radius` のミックスインを記述して、`$radius` パラメーターを設定してください。 前述の例にあるすべてのベンダープレフィックスを使用してください。 そして、`border-radius` ミックスインを使用して、`#awesome` 要素に `15px` の境界線半径を設定してください。
+Write a mixin named `shape` and give it 3 parameters: `$w`, `$h`, and `$bg-color`.
+
+Use the `shape` mixin to give the `#square` element a width and height of `50px`, and the color `red`. For the `#rect-a` element add a width of `100px`, a height of `50px`, and the color `blue`. Finally, for the `#rect-b` element add a width of `50px`, a height of `100px`, and the color `orange`.

-`$radius` というパラメーターを持つ `border-radius` というミックスインをコードで宣言します。
+You should declare a mixin named `shape` with 3 parameters: `$w`, `$h`, and `$bg-color`.
 
 ```js
-assert(code.match(/@mixin\s+?border-radius\s*?\(\s*?\$radius\s*?\)\s*?{/gi));
+assert.match(code, /@mixin\s+shape\s*\(\s*\$w,\s*\$h,\s*\$bg-color\s*\)\s*{/gi);
 ```
 
-`$radius` パラメーターを使用する `-webkit-border-radius` ベンダープレフィックスをコードに含めます。
+Your mixin should include a `width` property that uses the `$w` parameter.
 
 ```js
-assert(
-  __helpers.removeWhiteSpace(code).match(/-webkit-border-radius:\$radius;/gi)
-);
+assert.match(__helpers.removeWhiteSpace(code), /width:\$w;/gi);

+---
+
+# --description--
+Your game will be played against the computer. You will write a function that randomly returns `"rock"`, `"paper"` or `"scissors"`.
+
+You do not need to worry about the front-end part of the game. You will only write the logic for the game. Open the `script.js` and start following the instructions.
+
+**User stories:**
+
+1. You should have a function named `getComputerChoice`.
+
+1. Your `getComputerChoice` function should return `"rock"`, `"paper"`, or `"scissors"` at random.
+
+**Hint:** The [Math.random](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random) method returns a random number that’s greater than or equal to 0 and less than 1. Think about how you can use this to conditionally return one of the multiple choices.
+
+Your game will be played by a human player. You will write a function that takes the user's choice and returns it.
+
+1. Create a function named `getHumanChoice`.
+
+1. Write the code so that `getHumanChoice` will return one of the valid choices depending on what the user inputs.
+
+**Hint:** Use the [prompt](https://developer.mozilla.org/en-US/docs/Web/API/Window/prompt) method to get the user’s input.
+
+Your game will keep track of the player's score. You will write variables to keep track of the player's score.
+
+1. Create two new variables named `humanScore` and `computerScore` in the global scope.
+
+1. Initialize those variables with the value of `0`.
+
+Your game will be played round by round. You will write a function that takes the human and computer player choices as arguments, plays a single round, increments the round winner’s score and logs a winner announcement.
+
+1. Create a new function named `playRound`.
+
+1. Define two parameters for `playRound`. Parameter one `humanChoice` and parameter two `computerChoice`. Use these two parameters to take the human and computer choices as arguments.
+
+1. Make your function’s `humanChoice` parameter case-insensitive so that players can input `"rock"`, `"ROCK"`, `"RocK"`, or other variations.
+
+1. Write the code for your `playRound` function that returns a string value representing the round winner.
+
+- If it is a tie, it should return `"It's a tie!"`.
+
+- If the player wins, it should return `"You win! [player choice] beats [computer choice]"`.
+
+- If the computer wins, it should return `"You lose! [computer choice] beats [player choice]"`.
+
+1. Increment the `humanScore` or `computerScore` variable based on the round winner.
+
+Your game will play 3 rounds. You will write a function named `playGame` that calls `playRound` to play 3 rounds, keeps track of the scores, and declares a winner at the end.
+
+1. Create a new function named `playGame`.
+
+1. Create a loop that plays 3 rounds and calls the `playRound` function each time with the human's choice and the computer's choice functions as arguments.
+
+1. At the end of the game, return the winner of the game based on who won the most rounds.
+
+- If the human player wins more rounds than the computer player, return a message that says `"You win the game!"`.
+
+- If the computer player wins more rounds than the human player, return a message that says `"You lose the game!"`.
+

+```
+
+You should have a function called `getHumanChoice`
+
+```js

-In Sass, a <dfn>mixin</dfn> is a group of CSS declarations that can be reused throughout the style sheet.
-
-Newer CSS features take time before they are fully adopted and ready to use in all browsers. As features are added to browsers, CSS rules using them may need vendor prefixes. Consider `box-shadow`:
+In Sass, a <dfn>mixin</dfn> is a group of CSS declarations that can be reused throughout the style sheet. The definition starts with the `@mixin` at-rule, followed by a custom name. You apply the mixin using the `@include` at-rule.
 
 ```scss
-div {
-  -webkit-box-shadow: 0px 0px 4px #fff;
-  -moz-box-shadow: 0px 0px 4px #fff;
-  -ms-box-shadow: 0px 0px 4px #fff;
-  box-shadow: 0px 0px 4px #fff;
+@mixin reset-list {
+  margin: 0;
+  padding: 0;
+  list-style: none;
+}
+
+nav ul {
+  @include reset-list;
 }
 ```
 
-It's a lot of typing to re-write this rule for all the elements that have a `box-shadow`, or to change each value to test different effects. Mixins are like functions for CSS. Here is how to write one:
+Compiles to:
 
-```scss
-@mixin box-shadow($x, $y, $blur, $c){ 
-  -webkit-box-shadow: $x $y $blur $c;
-  -moz-box-shadow: $x $y $blur $c;
-  -ms-box-shadow: $x $y $blur $c;
-  box-shadow: $x $y $blur $c;
+```css
+nav ul {
+  margin: 0;
+  padding: 0;
+  list-style: none;
 }
 ```
 
-The definition starts with `@mixin` followed by a custom name. The parameters (the `$x`, `$y`, `$blur`, and `$c` in the example above) are optional. Now any time a `box-shadow` rule is needed, only a single line calling the mixin replaces having to type all the vendor prefixes. A mixin is called with the `@include` directive:
+Your mixins can also take arguments, which allows their behavior to be customized. The arguments are required when using the mixin.
 
 ```scss
-div {
-  @include box-shadow(0px, 0px, 4px, #fff);
+@mixin prose($font-size, $spacing) {
+  font-size: $font-size;
+  margin: 0;
+  margin-block-end: $spacing;
+}
+
+p {
+  @include prose(1.25rem, 1rem);
+}
+
+h2 {
+  @include prose(2.4rem, 1.5rem);
+}
+```
+
+You can make arguments optional by giving the parameters default values.
+
+```scss
+@mixin text-color($color: black) {
+  color: $color;
+}
+
+p {
+  @include text-color(); /* color: black */
+}
+
+nav a {
+  @include text-color(orange);
 }
 ```

-Write a mixin for `border-radius` and give it a `$radius` parameter. It should use all the vendor prefixes from the example. Then use the `border-radius` mixin to give the `#awesome` element a border radius of `15px`.
+Write a mixin named `shape` and give it 3 parameters: `$w`, `$h`, and `$bg-color`.
+
+Use the `shape` mixin to give the `#square` element a width and height of `50px`, and the color `red`. For the `#rect-a` element add a width of `100px`, a height of `50px`, and the color `blue`. Finally, for the `#rect-b` element add a width of `50px`, a height of `100px`, and the color `orange`.

+
+# --description--
+Your game will be played against the computer. You will write a function that randomly returns `"rock"`, `"paper"` or `"scissors"`.
+
+You do not need to worry about the front-end part of the game. You will only write the logic for the game. Open the `script.js` and start following the instructions.
+
+**User stories:**
+
+1. You should have a function named `getComputerChoice`.
+
+1. Your `getComputerChoice` function should return `"rock"`, `"paper"`, or `"scissors"` at random.
+
+**Hint:** The [Math.random](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random) method returns a random number that’s greater than or equal to 0 and less than 1. Think about how you can use this to conditionally return one of the multiple choices.
+
+Your game will be played by a human player. You will write a function that takes the user's choice and returns it.
+
+1. Create a function named `getHumanChoice`.
+
+1. Write the code so that `getHumanChoice` will return one of the valid choices depending on what the user inputs.
+
+**Hint:** Use the [prompt](https://developer.mozilla.org/en-US/docs/Web/API/Window/prompt) method to get the user’s input.
+
+Your game will keep track of the player's score. You will write variables to keep track of the player's score.
+
+1. Create two new variables named `humanScore` and `computerScore` in the global scope.
+
+1. Initialize those variables with the value of `0`.
+
+Your game will be played round by round. You will write a function that takes the human and computer player choices as arguments, plays a single round, increments the round winner’s score and logs a winner announcement.
+
+1. Create a new function named `playRound`.
+
+1. Define two parameters for `playRound`. Parameter one `humanChoice` and parameter two `computerChoice`. Use these two parameters to take the human and computer choices as arguments.
+
+1. Make your function’s `humanChoice` parameter case-insensitive so that players can input `"rock"`, `"ROCK"`, `"RocK"`, or other variations.
+
+1. Write the code for your `playRound` function that returns a string value representing the round winner.
+
+- If it is a tie, it should return `"It's a tie!"`.
+
+- If the player wins, it should return `"You win! [player choice] beats [computer choice]"`.
+
+- If the computer wins, it should return `"You lose! [computer choice] beats [player choice]"`.
+
+1. Increment the `humanScore` or `computerScore` variable based on the round winner.
+
+Your game will play 3 rounds. You will write a function named `playGame` that calls `playRound` to play 3 rounds, keeps track of the scores, and declares a winner at the end.
+
+1. Create a new function named `playGame`.
+
+1. Create a loop that plays 3 rounds and calls the `playRound` function each time with the human's choice and the computer's choice functions as arguments.
+
+1. At the end of the game, return the winner of the game based on who won the most rounds.
+
+- If the human player wins more rounds than the computer player, return a message that says `"You win the game!"`.
+
+- If the computer player wins more rounds than the human player, return a message that says `"You lose the game!"`.

+
+```js
+assert.equal(playRound("rock", "rock"), "It's a tie!");

+
+```js
+assert.equal(playRound("rock", "paper"), "You lose! paper beats rock");

-Em Sass, um <dfn>mixin</dfn> é um grupo de declarações CSS que podem ser reutilizados em toda a folha de estilos.
-
-Os recursos CSS mais recentes levam tempo antes de serem totalmente adotados e prontos para uso em todos os navegadores. Como recursos são adicionados aos navegadores, as regras CSS que os usam podem precisar de prefixos de fornecedores. Considere `box-shadow`:
+Em Sass, um <dfn>mixin</dfn> é um grupo de declarações CSS que podem ser reutilizados em toda a folha de estilos. A definição começa com a regra @ do `@mixin` seguida por um nome personalizado. Você aplica o mixin usando a regra `@include`.
 
 ```scss
-div {
-  -webkit-box-shadow: 0px 0px 4px #fff;
-  -moz-box-shadow: 0px 0px 4px #fff;
-  -ms-box-shadow: 0px 0px 4px #fff;
-  box-shadow: 0px 0px 4px #fff;
+@mixin reset-list {
+  margin: 0;
+  padding: 0;
+  list-style: none;
+}
+
+nav ul {
+  @include reset-list;
 }
 ```
 
-É preciso muita digitação para reescrever esta regra para todos os elementos que têm uma `box-shadow`, ou para alterar cada valor para testar efeitos diferentes. Mixins são como funções para CSS. Veja como escrever um:
+Compila para:
 
-```scss
-@mixin box-shadow($x, $y, $blur, $c){ 
-  -webkit-box-shadow: $x $y $blur $c;
-  -moz-box-shadow: $x $y $blur $c;
-  -ms-box-shadow: $x $y $blur $c;
-  box-shadow: $x $y $blur $c;
+```css
+nav ul {
+  margin: 0;
+  padding: 0;
+  list-style: none;
 }
 ```
 
-A definição começa com `@mixin` seguido por um nome personalizado. Os parâmetros (o `$x`, `$y`, `$blur`, e `$c` no exemplo acima) são opcionais. Agora, a qualquer momento que uma regra `box-shadow` é necessária, apenas uma única linha que chama o mixin substitui a necessidade de digitar todos os prefixos do fornecedor. Um mixin é chamado com a diretiva `@include`:
+Os mixins também podem receber argumentos, o que permite que seu comportamento seja personalizado. Os argumentos são necessários quando se utiliza o mixin.
 
 ```scss
-div {
-  @include box-shadow(0px, 0px, 4px, #fff);
+@mixin prose($font-size, $spacing) {
+  font-size: $font-size;
+  margin: 0;
+  margin-block-end: $spacing;
+}
+
+p {
+  @include prose(1.25rem, 1rem);
+}
+
+h2 {
+  @include prose(2.4rem, 1.5rem);
+}
+```
+
+Você pode tornar os argumentos opcionais dando valores padrão aos parâmetros.
+
+```scss
+@mixin text-color($color: black) {
+  color: $color;
+}
+
+p {
+  @include text-color(); /* color: black */
+}
+
+nav a {
+  @include text-color(orange);
 }
 ```
 
 # --instructions--
 
-Escreva um mixin para `border-radius` e dê a ele o parâmetro `$radius`. Deve usar todos os prefixos de fornecedor do exemplo. Em seguida, use o mixin de `border-radius` para dar ao elemento `#awesome` um raio de borda de `15px`.
+Escreva um mixin chamado `shape` e dê a ele 3 parâmetros: `$w`, `$h` e `$bg-color`.
+
+Use o mixin `shape` para dar ao elemento `#square` uma largura (w) e uma altura (h) de `50px`, e a cor de fundo `red` (vermelha). Para o elemento `#rect-a`, adicione uma largura (w) de `100px`, uma altura (h) de `50px` e a cor de fundo `blue` (azul). Finalmente, para o elemento `#rect-b`, adicione uma largura (w) de `50px`, uma altura (h) de `100px` e a cor de fundo `orange` (laranja).

+
+# --description--
+Your game will be played against the computer. You will write a function that randomly returns `"rock"`, `"paper"` or `"scissors"`.
+
+You do not need to worry about the front-end part of the game. You will only write the logic for the game. Open the `script.js` and start following the instructions.
+
+**User stories:**
+
+1. You should have a function named `getComputerChoice`.
+
+1. Your `getComputerChoice` function should return `"rock"`, `"paper"`, or `"scissors"` at random.
+
+**Hint:** The [Math.random](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random) method returns a random number that’s greater than or equal to 0 and less than 1. Think about how you can use this to conditionally return one of the multiple choices.
+
+Your game will be played by a human player. You will write a function that takes the user's choice and returns it.
+
+1. Create a function named `getHumanChoice`.
+
+1. Write the code so that `getHumanChoice` will return one of the valid choices depending on what the user inputs.
+
+**Hint:** Use the [prompt](https://developer.mozilla.org/en-US/docs/Web/API/Window/prompt) method to get the user’s input.
+
+Your game will keep track of the player's score. You will write variables to keep track of the player's score.
+
+1. Create two new variables named `humanScore` and `computerScore` in the global scope.
+
+1. Initialize those variables with the value of `0`.
+
+Your game will be played round by round. You will write a function that takes the human and computer player choices as arguments, plays a single round, increments the round winner’s score and logs a winner announcement.
+
+1. Create a new function named `playRound`.
+
+1. Define two parameters for `playRound`. Parameter one `humanChoice` and parameter two `computerChoice`. Use these two parameters to take the human and computer choices as arguments.
+
+1. Make your function’s `humanChoice` parameter case-insensitive so that players can input `"rock"`, `"ROCK"`, `"RocK"`, or other variations.
+
+1. Write the code for your `playRound` function that returns a string value representing the round winner.
+
+- If it is a tie, it should return `"It's a tie!"`.
+
+- If the player wins, it should return `"You win! [player choice] beats [computer choice]"`.
+
+- If the computer wins, it should return `"You lose! [computer choice] beats [player choice]"`.
+
+1. Increment the `humanScore` or `computerScore` variable based on the round winner.
+
+Your game will play 3 rounds. You will write a function named `playGame` that calls `playRound` to play 3 rounds, keeps track of the scores, and declares a winner at the end.
+
+1. Create a new function named `playGame`.
+
+1. Create a loop that plays 3 rounds and calls the `playRound` function each time with the human's choice and the computer's choice functions as arguments.
+
+1. At the end of the game, return the winner of the game based on who won the most rounds.
+
+- If the human player wins more rounds than the computer player, return a message that says `"You win the game!"`.
+
+- If the computer player wins more rounds than the human player, return a message that says `"You lose the game!"`.

-In Sass, a <dfn>mixin</dfn> is a group of CSS declarations that can be reused throughout the style sheet.
-
-Newer CSS features take time before they are fully adopted and ready to use in all browsers. As features are added to browsers, CSS rules using them may need vendor prefixes. Consider `box-shadow`:
+In Sass, a <dfn>mixin</dfn> is a group of CSS declarations that can be reused throughout the style sheet. The definition starts with the `@mixin` at-rule, followed by a custom name. You apply the mixin using the `@include` at-rule.
 
 ```scss
-div {
-  -webkit-box-shadow: 0px 0px 4px #fff;
-  -moz-box-shadow: 0px 0px 4px #fff;
-  -ms-box-shadow: 0px 0px 4px #fff;
-  box-shadow: 0px 0px 4px #fff;
+@mixin reset-list {
+  margin: 0;
+  padding: 0;
+  list-style: none;
+}
+
+nav ul {
+  @include reset-list;
 }
 ```
 
-It's a lot of typing to re-write this rule for all the elements that have a `box-shadow`, or to change each value to test different effects. Mixins are like functions for CSS. Here is how to write one:
+Compiles to:
 
-```scss
-@mixin box-shadow($x, $y, $blur, $c){ 
-  -webkit-box-shadow: $x $y $blur $c;
-  -moz-box-shadow: $x $y $blur $c;
-  -ms-box-shadow: $x $y $blur $c;
-  box-shadow: $x $y $blur $c;
+```css
+nav ul {
+  margin: 0;
+  padding: 0;
+  list-style: none;
 }
 ```
 
-The definition starts with `@mixin` followed by a custom name. The parameters (the `$x`, `$y`, `$blur`, and `$c` in the example above) are optional. Now any time a `box-shadow` rule is needed, only a single line calling the mixin replaces having to type all the vendor prefixes. A mixin is called with the `@include` directive:
+Your mixins can also take arguments, which allows their behavior to be customized. The arguments are required when using the mixin.
 
 ```scss
-div {
-  @include box-shadow(0px, 0px, 4px, #fff);
+@mixin prose($font-size, $spacing) {
+  font-size: $font-size;
+  margin: 0;
+  margin-block-end: $spacing;
+}
+
+p {
+  @include prose(1.25rem, 1rem);
+}
+
+h2 {
+  @include prose(2.4rem, 1.5rem);
+}
+```
+
+You can make arguments optional by giving the parameters default values.
+
+```scss
+@mixin text-color($color: black) {
+  color: $color;
+}
+
+p {
+  @include text-color(); /* color: black */
+}
+
+nav a {
+  @include text-color(orange);
 }
 ```
 
 # --instructions--
 
-Write a mixin for `border-radius` and give it a `$radius` parameter. It should use all the vendor prefixes from the example. Then use the `border-radius` mixin to give the `#awesome` element a border radius of `15px`.
+Write a mixin named `shape` and give it 3 parameters: `$w`, `$h`, and `$bg-color`.
+
+Use the `shape` mixin to give the `#square` element a width and height of `50px`, and the color `red`. For the `#rect-a` element add a width of `100px`, a height of `50px`, and the color `blue`. Finally, for the `#rect-b` element add a width of `50px`, a height of `100px`, and the color `orange`.
 
 # --hints--
 
-Your code should declare a mixin named `border-radius` which has a parameter named `$radius`.
+You should declare a mixin named `shape` with 3 parameters: `$w`, `$h`, and `$bg-color`.

 ```
 
-Your code should include the `-webkit-border-radius` vendor prefix that uses the `$radius` parameter.

-);
+assert.match(__helpers.removeWhiteSpace(code), /width:\$w;/gi);
 ```
 
-Your code should include the `-moz-border-radius` vendor prefix that uses the `$radius` parameter.

 ```js

 ```
 
-Your code should include the `-ms-border-radius` vendor prefix that uses the `$radius` parameter.

+In the block of the `default` case, set the `textContent` property of `currentDateParagraph` to `formattedDate`.

+title: Build a Rock Paper Scissors Game
+challengeType: 14
+dashedName: top-build-a-rock-paper-scissors-game
+---
+
+# --description--
+Your game will be played against the computer. You will write a function that randomly returns `"rock"`, `"paper"` or `"scissors"`.
+
+You do not need to worry about the front-end part of the game. You will only write the logic for the game. Open the `script.js` and start following the instructions.
+
+**User stories:**
+
+1. You should have a function named `getComputerChoice`.
+
+1. Your `getComputerChoice` function should return `"rock"`, `"paper"`, or `"scissors"` at random.
+
+**Hint:** The [Math.random](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random) method returns a random number that’s greater than or equal to 0 and less than 1. Think about how you can use this to conditionally return one of the multiple choices.
+
+Your game will be played by a human player. You will write a function that takes the user's choice and returns it.
+
+1. Create a function named `getHumanChoice`.
+
+1. Write the code so that `getHumanChoice` will return one of the valid choices depending on what the user inputs.
+
+**Hint:** Use the [prompt](https://developer.mozilla.org/en-US/docs/Web/API/Window/prompt) method to get the user’s input.
+
+Your game will keep track of the player's score. You will write variables to keep track of the player's score.
+
+1. Create two new variables named `humanScore` and `computerScore` in the global scope.
+
+1. Initialize those variables with the value of `0`.
+
+Your game will be played round by round. You will write a function that takes the human and computer player choices as arguments, plays a single round, increments the round winner’s score and logs a winner announcement.
+
+1. Create a new function named `playRound`.
+
+1. Define two parameters for `playRound`. Parameter one `humanChoice` and parameter two `computerChoice`. Use these two parameters to take the human and computer choices as arguments.
+
+1. Make your function’s `humanChoice` parameter case-insensitive so that players can input `"rock"`, `"ROCK"`, `"RocK"`, or other variations.
+
+1. Write the code for your `playRound` function that returns a string value representing the round winner.
+
+- If it is a tie, it should return `"It's a tie!"`.
+
+- If the player wins, it should return `"You win! [player choice] beats [computer choice]"`.
+
+- If the computer wins, it should return `"You lose! [computer choice] beats [player choice]"`.
+
+1. Increment the `humanScore` or `computerScore` variable based on the round winner.
+
+Your game will play 3 rounds. You will write a function named `playGame` that calls `playRound` to play 3 rounds, keeps track of the scores, and declares a winner at the end.
+
+1. Create a new function named `playGame`.
+
+1. Create a loop that plays 3 rounds and calls the `playRound` function each time with the human's choice and the computer's choice functions as arguments.
+
+1. At the end of the game, return the winner of the game based on who won the most rounds.
+
+- If the human player wins more rounds than the computer player, return a message that says `"You win the game!"`.
+
+- If the computer player wins more rounds than the human player, return a message that says `"You lose the game!"`.
+
+# --hints--
+
+You should have a function called `getComputerChoice`
+
+```js
+assert.isFunction(getComputerChoice);
+```
+
+Your `getComputerChoice` function should return `"rock"`, `"paper"`, or `"scissors"` at random.
+
+```js
+const counts = {}
+for (let i = 0; i < 100; i++) {
+  const result = getComputerChoice();
+  counts[result] = (counts[result] ?? 0) + 1;
+}
+assert.lengthOf(Object.keys(counts), 3);
+assert.include(Object.keys(counts), "rock");
+assert.include(Object.keys(counts), "paper");

+
+You should have two variables named `humanScore` and `computerScore` in the global scope.
+
+```js
+assert.exists(humanScore);
+assert.exists(computerScore);
+```
+
+You should have a function called `playRound`
+
+```js
+assert.isFunction(playRound);
+```
+
+Your `playRound` function should take the human and computer player choices as arguments with the parameters `humanChoice` and `computerChoice`.
+
+```js
+assert.match(playRound.toString(), /\s*(?:\bhumanChoice\b\s*,\s*\bcomputerChoice\b)/);
+```
+
+Your `playRound` function should be case-insensitive so that players can input `"rock"`, `"ROCK"`, `"RocK"`, or other variations.
+
+```js
+assert.match(playRound.toString(), /\bhumanChoice\s*\.toLowerCase\(\)/);
+```
+
+Your `playRound` function should return the string `"It's a tie!"` if the human and computer choices are the same.
+
+```js
+assert.equal(playRound("rock", "rock"), "It's a tie!");
+```
+
+Your `playRound` function should return the string `"You win! [player choice] beats [computer choice]"` if the player wins.
+
+```js
+assert.equal(playRound("rock", "scissors"), "You win! rock beats scissors");
+```
+
+Your `playRound` function should return the string `"You lose! [computer choice] beats [player choice]"` if the computer wins.
+
+```js
+assert.equal(playRound("rock", "paper"), "You lose! paper beats rock");
+```
+
+Your `playRound` function should increment the `humanScore` or `computerScore` variable based on the round winner.
+
+```js
+humanScore = 0;
+computerScore = 0;
+playRound("rock", "scissors");
+assert.equal(humanScore, 1);
+```
+
+You should have a function called `playGame`.

 # --description--
 
-<dfn>Міксин</dfn> у Sass — це група оголошень CSS, які можна повторно використовувати у таблиці стилів.
-
-Новіші функції CSS потребують трохи часу, перш ніж вони будуть повністю прийнятними та готовими до використання у всіх браузерах. Як тільки функції додано до браузерів, то правилам CSS, які використовують їх, можливо, знадобляться вендорні префікси. Розглянемо `box-shadow`:
+In Sass, a <dfn>mixin</dfn> is a group of CSS declarations that can be reused throughout the style sheet. The definition starts with the `@mixin` at-rule, followed by a custom name. You apply the mixin using the `@include` at-rule.
 
 ```scss
-div {
-  -webkit-box-shadow: 0px 0px 4px #fff;
-  -moz-box-shadow: 0px 0px 4px #fff;
-  -ms-box-shadow: 0px 0px 4px #fff;
-  box-shadow: 0px 0px 4px #fff;
+@mixin reset-list {
+  margin: 0;
+  padding: 0;
+  list-style: none;
+}
+
+nav ul {
+  @include reset-list;
 }
 ```
 
-Потрібно написати багато тексту, щоб переписати правило для всіх елементів, які мають `box-shadow`, чи щоб змінити кожне значення для перевірки різних ефектів. Міксини — це як функції для CSS. Ось приклад як написати один з них:
+Compiles to:
 
-```scss
-@mixin box-shadow($x, $y, $blur, $c){ 
-  -webkit-box-shadow: $x $y $blur $c;
-  -moz-box-shadow: $x $y $blur $c;
-  -ms-box-shadow: $x $y $blur $c;
-  box-shadow: $x $y $blur $c;
+```css
+nav ul {
+  margin: 0;
+  padding: 0;
+  list-style: none;
 }
 ```
 
-Визначення починається з `@mixin`, після якого пишуть назву. Параметри (`$x`, `$y`, `$blur` та `$c` у прикладі вище) необов’язкові. Тепер, якщо нам знадобиться правило `box-shadow`, то лише один рядок, який викличе міксин, замінює необхідність написання усіх вендорних префіксів. Міксин викликається директивою `@include`:
+Your mixins can also take arguments, which allows their behavior to be customized. The arguments are required when using the mixin.
 
 ```scss
-div {
-  @include box-shadow(0px, 0px, 4px, #fff);
+@mixin prose($font-size, $spacing) {
+  font-size: $font-size;
+  margin: 0;
+  margin-block-end: $spacing;
+}
+
+p {
+  @include prose(1.25rem, 1rem);
+}
+
+h2 {
+  @include prose(2.4rem, 1.5rem);
+}
+```
+
+You can make arguments optional by giving the parameters default values.
+
+```scss
+@mixin text-color($color: black) {
+  color: $color;
+}
+
+p {
+  @include text-color(); /* color: black */
+}
+
+nav a {
+  @include text-color(orange);
 }
 ```
 
 # --instructions--
 
-Напишіть міксин для `border-radius` і надайте йому параметр `$radius`. Він має використати усі вендорні префікси з прикладу. Після цього використайте міксин `border-radius`, щоб надати елементу `#awesome` заокруглений радіус зі значенням `15px`.
+Write a mixin named `shape` and give it 3 parameters: `$w`, `$h`, and `$bg-color`.
+
+Use the `shape` mixin to give the `#square` element a width and height of `50px`, and the color `red`. For the `#rect-a` element add a width of `100px`, a height of `50px`, and the color `blue`. Finally, for the `#rect-b` element add a width of `50px`, a height of `100px`, and the color `orange`.

+
+# --description--
+У грі буде двоє гравців: людина і комп’ютер. Ви напишете функцію, яка випадковим чином повертає `"rock"`, `"paper"` або `"scissors"`.
+
+Не турбуйтесь про фронт енд гри. Ви писатимете лише логіку гри. Відкрийте `script.js` та дотримуйтесь інструкцій нижче.
+
+**Історія користувача:**
+
+1. Ви повинні мати функцію під назвою `getComputerChoice`.
+
+1. Функція `getComputerChoice` має повернути `"rock"`, `"paper"` або `"scissors"` (випадковим чином).
+
+**Підказка:** метод [Math.random](https://webdoky.org/uk/docs/Web/JavaScript/Reference/Global_Objects/Math/random/) повертає випадкове число, яке більше або дорівнює 0, але менше за 1. Подумайте, як його можна використати, щоб умовно повернути один з декількох виборів.
+
+Гру гратиме людина. Ви напишете функцію, яка приймає вибір користувача та повертає його.
+
+1. Створіть функцію під назвою `getHumanChoice`.
+
+1. Напишіть такий код, щоб функція `getHumanChoice` повернула один з дійсних виборів залежно від вхідних даних користувача.
+
+**Підказка:** використайте метод [prompt](https://developer.mozilla.org/en-US/docs/Web/API/Window/prompt), щоб отримати вхідні дані користувача.
+
+Гра вестиме рахунок. Для цього ви напишете змінні.
+
+1. У глобальній області створіть дві змінні під назвами `humanScore` та `computerScore`.
+
+1. Надайте цим змінним значення `0`.
+
+Після кожного раунду буде інший. Ви напишете функцію, яка приймає вибори гравців як аргументи, грає один раунд, збільшує очки переможця та оголошує переможця.
+
+1. Створіть нову функцію під назвою `playRound`.
+
+1. Визначте два параметри для `playRound`: `humanChoice` та `computerChoice`. Використайте ці два параметри, щоб прийняти вибори людини та комп’ютера як аргументи.
+
+1. Зробіть параметр `humanChoice` нечутливим до регістру, щоб гравці могли вводити `"rock"`, `"ROCK"`, `"RocK"` чи інші варіанти.
+
+1. Напишіть код для функції `playRound`, що повертає рядок із переможцем раунду.
+
+- Якщо нічия, вона має повернути `"It's a tie!"`.
+
+- Якщо перемогла людина, вона має повернути `"You win! [player choice] beats [computer choice]"`.
+
+- Якщо переміг комп’ютер, вона має повернути `"You lose! [computer choice] beats [player choice]"`.
+
+1. Збільште змінну `humanScore` або `computerScore` залежно від переможця раунду.
+
+Гра складається з 3 раундів. Ви напишете функцію `playGame`, яка викликає `playRound`, щоб зіграти 3 раунди, веде рахунок та оголошує переможця вкінці.
+
+1. Створіть нову функцію під назвою `playGame`.
+
+1. Створіть цикл, який грає 3 раунди і кожного разу викликає функцію `playRound`, аргументами якої є вибори людини та комп’ютера.
+
+1. У кінці гри поверніть переможця гри на основі того, хто виграв більше раундів.
+
+- Якщо людина перемагає більше раундів, ніж комп’ютер, поверніть повідомлення `"You win the game!"`.
+
+- Якщо комп’ютер перемагає більше раундів, ніж людина, поверніть повідомлення `"You lose the game!"`.
