## Description
<section id="description">您也可以在<code>form</code>元素上使用Bootstrap的<code>col-xs-*</code>类！这样，无论屏幕分辨率有多宽，我们的复选框都会均匀分布在整个页面上。将所有三个复选框嵌套在<code>&lt;div class=&quot;row&quot;&gt;</code>元素中。然后将它们嵌套在<code>&lt;div class=&quot;col-xs-4&quot;&gt;</code>元素中。 </section>

## Tests
<section id='tests'>

```yml
tests:
  - text: 将所有复选框<code>div</code>带有类<code>row</code> <code>div</code> 。
    testString: assert($("div.row:has(input[type=\"checkbox\"])").length > 0);
  - text: 使用类<code>col-xs-4</code>将每个复选框嵌入其自己的<code>div</code> 。
    testString: assert($("div.col-xs-4:has(input[type=\"checkbox\"])").length > 2);
  - text: 确保每个<code>div</code>元素都有一个结束标记。
    testString: assert(code.match(/<\/div>/g) && code.match(/<div/g) && code.match(/<\/div>/g).length === code.match(/<div/g).length);
