# --description--
|

|
|
|
||
|
|
Bootstrap には、`button` 要素用に独自のスタイルが用意されており、プレーンな HTML のボタンよりもずっと良い見栄えで表示されます。
|
||
|
|
|
||
|
|
大きな子猫の写真の下に、新しい `button` 要素を作成してください。 ボタンには `btn` クラスと `btn-default` クラスを付け、`Like` というテキストも設定してください。
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
`Like` というテキストを持つ新しい `button` 要素を作成します。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(
|
||
|
|
new RegExp('like', 'gi').test($('button').text()) &&
|
||
|
|
$('img.img-responsive + button.btn').length > 0
|
||
|
|
);
|
||
|
|
```
|
||
|
|
|
||
|
|
新しいボタンには `btn` と `btn-default` の 2 つのクラスが必要です。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert($('button').hasClass('btn') && $('button').hasClass('btn-default'));
|
||
|
|
```
|
||
|
|
|
||
|
|
`button` 要素にはすべて終了タグが必要です。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(
|
||
|
|
code.match(/<\/button>/g) &&
|
||
|
|
code.match(/<button/g) &&
|
||
|
|
code.match(/<\/button>/g).length === code.match(/<button/g).length
|
||
|
|
);
|
||
|
|
```
|
||
