# --description--
|
||
|
||
Bootstrap 還有另外一種按鈕 class 屬性叫做 `btn-default`。
|
||
|
||
爲所有的 `button` 元素增加兩個 class： `btn` 和 `btn-default`。
|
||
|
||
# --hints--
|
||
|
||
應該將 `btn` class 添加到所有的 `button` 元素中。
|
||
|
||
```js
|
||
assert($('.btn').length > 5);
|
||
```
|
||
|
||
應該將 `btn-default` class 添加到每一個 `button` 元素中。
|
||
|
||
```js
|
||
assert($('.btn-default').length > 5);
|
||
```
