# --description--
|
||
|
|
||
|
Bootstrap の `col-xs-*` クラスはすべての `form` 要素に適用できるので、チェックボックスにも使用できます。 この方法では、画面解像度の幅に関係なく、チェックボックスがページ全体に等間隔で表示されます。
|
||
|
|
||
|
# --instructions--
|
||
|
|
||
|
3 つすべてのチェックボックスを `<div class="row">` 要素の中に入れてください。 次に、各チェックボックスを `<div class="col-xs-4">` 要素の中に入れてください。
|
||
|
|
||
|
# --hints--
|
||
|
|
||
|
すべてのチェックボックスを、クラス `row` を持つ 1 つの `div` の内側に入れます。
|
||
|
|
||
|
```js
|
||
|
assert($('div.row:has(input[type="checkbox"])').length > 0);
|
||
|
```
|
||
|
|
||
|
各チェックボックスを、クラス `col-xs-4` を持つ自身の `div` の内側に入れます。
|
||
|
|
||
|
```js
|
||
|
assert($('div.col-xs-4:has(input[type="checkbox"])').length > 2);
|
||
|
```
|
||
|
|
||
|
`div` 要素にはすべて終了タグが必要です。
|
||
|
|
||
|
```js
|
||
|
assert(
|
||
|
code.match(/<\/div>/g) &&
|
||
|
code.match(/<div/g) &&
|
||
|
code.match(/<\/div>/g).length === code.match(/<div/g).length
|
||
|
);
|
||
|
```
