# --description--
**Objective:** Fulfill the user stories below and get all the tests to pass to complete the lab.
**User Stories:**
1. Your tribute page should have a `main` element with a corresponding `id` of `main`, which contains all other elements.
1. You should see an element with an `id` of `title`, which contains a string (i.e. text), that describes the subject of the tribute page (e.g. "Dr. Norman Borlaug").
1. You should see either a `figure` or a `div` element with an `id` of `img-div`.
1. Within the `#img-div` element, you should see an `img` element with a corresponding `id="image"`.
1. Within the `#img-div` element, you should see an element with a corresponding `id="img-caption"` that contains textual content describing the image shown in `#img-div`.
1. You should see an element with a corresponding `id="tribute-info"`, which contains textual content describing the subject of the tribute page.
1. You should see an `a` element with a corresponding `id="tribute-link"`, which links to an outside site, that contains additional information about the subject of the tribute page. HINT: You must give your element an attribute of `target` and set it to `_blank` in order for your link to open in a new tab.
1. Your `#image` should use `max-width` and `height` properties to resize responsively, relative to the width of its parent element, without exceeding its original size.
1. Your `img` element should be centered within its parent element.
**Note:** Be sure to link your stylesheet in your HTML and apply your CSS.
# --hints--
You should have a `main` element with an `id` of `main`.
```js
const el = document.getElementById('main')
assert(!!el && el.tagName === 'MAIN')
```
Your `#img-div`, `#image`, `#img-caption`, `#tribute-info`, and `#tribute-link` should all be descendants of `#main`.
```js
const el1 = document.querySelector('#main #img-div')
const el2 = document.querySelector('#main #image')
const el3 = document.querySelector('#main #img-caption')
const el4 = document.querySelector('#main #tribute-info')
const el5 = document.querySelector('#main #tribute-link')
assert(!!el1 & !!el2 && !!el3 && !!el4 && !!el5)
```
You should have an element with an `id` of `title`.
```js
const el = document.getElementById('title')
assert(!!el)
```
Your `#title` should not be empty.
```js
const el = document.getElementById('title')
assert(!!el && el.innerText.length > 0)
```
You should have a `figure` or `div` element with an `id` of `img-div`.
```js
const el = document.getElementById('img-div')
assert(!!el && (el.tagName === 'DIV' || el.tagName === 'FIGURE'))
```
You should have an `img` element with an `id` of `image`.
```js
const el = document.getElementById('image')
assert(!!el && el.tagName === 'IMG')
```
Your `#image` should be a descendant of `#img-div`.
```js
const el = document.querySelector('#img-div #image')
assert(!!el)
```
You should have a `figcaption` or `div` element with an `id` of `img-caption`.
```js
const el = document.getElementById('img-caption')
assert(!!el && (el.tagName === 'DIV' || el.tagName === 'FIGCAPTION'))
```
Your `#img-caption` should be a descendant of `#img-div`.
```js
const el = document.querySelector('#img-div #img-caption')
assert(!!el)
```
Your `#img-caption` should not be empty.
```js
const el = document.getElementById('img-caption')
assert(!!el && el.innerText.length > 0)
```
You should have an element with an `id` of `tribute-info`.
```js
const el = document.getElementById('tribute-info')
assert(!!el)
```
Your `#tribute-info` should not be empty.
```js
const el = document.getElementById('tribute-info')
assert(!!el && el.innerText.length > 0)
```
You should have an `a` element with an `id` of `tribute-link`.
```js
const el = document.getElementById('tribute-link')
assert(!!el && el.tagName === 'A')
```
Your `#tribute-link` should have an `href` attribute and value.
```js
const el = document.getElementById('tribute-link')
assert(!!el && !!el.href && el.href.length > 0)
```
Your `#tribute-link` should have a `target` attribute set to `_blank`.
```js
const el = document.getElementById('tribute-link')
assert(!!el && el.target === '_blank')
```
Your `img` element should have a `display` of `block`.
```js
const img = document.getElementById('image');
const imgStyle = window.getComputedStyle(img);
const style = imgStyle?.getPropertyValue('display')
assert(style === 'block')
```
Your `#image` should have a `max-width` of `100%`.
```js
const img = document.getElementById('image');
const imgStyle = window.getComputedStyle(img);
const style = imgStyle?.getPropertyValue('max-width')
assert(style === '100%')
```
Your `#image` should have a `height` of `auto`.
```js
// taken from the testable-projects repo
const img = document.getElementById('image');
const imgStyle = window.getComputedStyle(img);
const oldDisplayValue = imgStyle.getPropertyValue('display');
const oldDisplayPriority = imgStyle.getPropertyPriority('display');
img?.style.setProperty('display', 'none', 'important');
const heightValue = imgStyle?.getPropertyValue('height')
img?.style.setProperty('display', oldDisplayValue, oldDisplayPriority);
assert(heightValue === 'auto')
```
Your `#image` should be centered within its parent.
```js
// taken from the testable-projects repo
const img = document.getElementById('image'),
imgParent = img?.parentElement,
imgLeft = img?.getBoundingClientRect().left,
imgRight = img?.getBoundingClientRect().right,
parentLeft = imgParent?.getBoundingClientRect().left,
parentRight = imgParent?.getBoundingClientRect().right,
leftMargin = imgLeft - parentLeft,
rightMargin = parentRight - imgRight;
assert(leftMargin - rightMargin < 6 && rightMargin - leftMargin < 6)
```

<section id="tribute-info">
<h3 id="headline">Here's a time line of Dr. Borlaug's life:</h3>
<ul>
<li><strong>1914</strong> - Born in Cresco, Iowa</li>
<li>
<strong>1933</strong> - Leaves his family's farm to attend the
University of Minnesota, thanks to a Depression era program known as
the "National Youth Administration"
</li>
<li>
<strong>1935</strong> - Has to stop school and save up more money.
Works in the Civilian Conservation Corps, helping starving
Americans. "I saw how food changed them", he said. "All of this left
scars on me."
</li>
<li>
<strong>1937</strong> - Finishes university and takes a job in the
US Forestry Service
</li>
<li>
<strong>1938</strong> - Marries wife of 69 years Margret Gibson.
Gets laid off due to budget cuts. Inspired by Elvin Charles Stakman,
he returns to school study under Stakman, who teaches him about
breeding pest-resistent plants.
</li>
<li>
<strong>1941</strong> - Tries to enroll in the military after the
Pearl Harbor attack, but is rejected. Instead, the military asked
his lab to work on waterproof glue, DDT to control malaria,
disinfectants, and other applied science.
</li>
<li>
<strong>1942</strong> - Receives a Ph.D. in Genetics and Plant
Pathology
</li>
<li>
<strong>1944</strong> - Rejects a 100% salary increase from Dupont,
leaves behind his pregnant wife, and flies to Mexico to head a new
plant pathology program. Over the next 16 years, his team breeds
6,000 different strains of disease resistent wheat - including
different varieties for each major climate on Earth.
</li>
<li>
<strong>1945</strong> - Discovers a way to grown wheat twice each
season, doubling wheat yields
</li>
<li>
<strong>1953</strong> - crosses a short, sturdy dwarf breed of wheat
with a high-yeidling American breed, creating a strain that responds
well to fertilizer. It goes on to provide 95% of Mexico's wheat.
</li>
<li>
<strong>1962</strong> - Visits Delhi and brings his high-yielding
strains of wheat to the Indian subcontinent in time to help mitigate
mass starvation due to a rapidly expanding population
</li>
<li><strong>1970</strong> - receives the Nobel Peace Prize</li>
<li>
<strong>1983</strong> - helps seven African countries dramatically
increase their maize and sorghum yields
</li>
<li>
<strong>1984</strong> - becomes a distinguished professor at Texas
A&M University
</li>
<li>
<strong>2005</strong> - states "we will have to double the world
food supply by 2050." Argues that genetically modified crops are the
only way we can meet the demand, as we run out of arable land. Says
that GM crops are not inherently dangerous because "we've been
genetically modifying plants and animals for a long time. Long
before we called it science, people were selecting the best breeds."
</li>
<li><strong>2009</strong> - dies at the age of 95.</li>
