# --description--

일반적으로 `btn`클래스와 `btn-default` 클래스가 적용된 `button` 요소는, 버튼 안에 담겨진 텍스트 길이만큼의 너비를 차지합니다. 예를 들어:

```html
<button class="btn btn-default">Submit</button>
```

이 버튼은 `Submit`이라는 단어만큼의 너비만을 차지합니다.

<button class='btn btn-default'>Submit</button>

`btn-block`이라는 클래스를 버튼 요소에 추가해줌으로써 버튼을 블록 레벨 요소로 만들 수 있습니다. 버튼은 페이지의 가로 공간을 꽉 채워 차지하게 됩니다. 버튼 뒤에 나오는 요소들은, 버튼 아래의 새로운 줄에 배치됩니다.

```html
<button class="btn btn-default btn-block">Submit</button>
```

이 버튼은 사용 가능한 너비의 100%를 차지할 것입니다.

<button class='btn btn-default btn-block'>Submit</button>

버튼에는 여전히 `btn` 클래스가 있어야 합니다.

부트스트랩 버튼에 `btn-block` 클래스를 추가해보세요.

# --hints--

버튼에는 여전히 `btn` 클래스와 `btn-default` 클래스가 있어야 합니다.

```js
assert($('button').hasClass('btn') && $('button').hasClass('btn-default'));
```

버튼에는 `btn-block` 클래스가 있어야 합니다.

```js
assert($('button').hasClass('btn-block'));
```

모든 `button` 요소들에는 닫는 태그가 있어야 합니다.

```js
assert(
  code.match(/<\/button>/g) &&
    code.match(/<button/g) &&
    code.match(/<\/button>/g).length === code.match(/<button/g).length
);
```
