# --description--
Bootstrap 的 `button` 元素有着獨有的、比默認 HTML 按鈕更好的樣式風格。
在較大的小貓圖片下方創建新的 `button` 元素。 爲它添加 `btn` 與 `btn-default` 兩個 classes 和 `Like` 文本。
# --hints--
應創建一個新的包含 `Like` 文本的 `button` 元素。
```js
assert(
new RegExp('like', 'gi').test($('button').text()) & &
$('img.img-responsive + button.btn').length > 0
);
```
新的按鈕元素應該有兩個 classes: `btn` 和 `btn-default` 。
```js
assert($('button').hasClass('btn') & & $('button').hasClass('btn-default'));
```

確保所有 `button` 元素都有閉合標籤。

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