 | ||
|  | 
 | ||
|  | 通常、`btn` および `btn-default` クラスを持つ `button` 要素の幅は、それらが含まれているテキストと同じ幅にしかなりません。 例: | ||
|  | 
 | ||
|  | ```html | ||
|  | <button class="btn btn-default">Submit</button> | ||
|  | ``` | ||
|  | 
 | ||
|  | このボタンは単語 `Submit` と同じ幅になります。 | ||
|  | 
 | ||
|  | <button class='btn btn-default'>Submit</button> | ||
|  | 
 | ||
|  | クラス `btn-block` を追加してブロック要素にすることで、ボタンがページの水平方向のスペース全体を埋めるように広がり、その後に続く要素はすべてブロックの下の「新しい行」に表示されます。 | ||
|  | 
 | ||
|  | ```html | ||
|  | <button class="btn btn-default btn-block">Submit</button> | ||
|  | ``` | ||
|  | 
 | ||
|  | このボタンは利用可能な幅全体に広がって表示されます。 | ||
|  | 
 | ||
|  | <button class='btn btn-default btn-block'>Submit</button> | ||
|  | 
 | ||
|  | これらのボタンにも `btn` クラスが必要であることに注意してください。 | ||
|  | 
 | ||
|  | Bootstrap の `btn-block` クラスを Bootstrap ボタンに追加してください。 | ||
|  | 
 | ||
|  | # --hints--
 | ||
|  | 
 | ||
|  | ボタンには `btn` クラスと `btn-default` クラスを持たせる必要もあります。 | ||
|  | 
 | ||
|  | ```js | ||
|  | assert($('button').hasClass('btn') && $('button').hasClass('btn-default')); | ||
|  | ``` | ||
|  | 
 | ||
|  | ボタンにクラス `btn-block` を持たせます。 | ||
|  | 
 | ||
|  | ```js | ||
|  | assert($('button').hasClass('btn-block')); | ||
|  | ``` | ||
|  | 
 | ||
|  | `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 | ||
|  | ); | ||
|  | ``` | ||
