title: 使用 hr 标签创建水平线
|
||
---
|
||
|
||
## Description
|
||
<section id='description'>
|
||
术语：Horizontal Rule => hr => 水平线。
|
||
你可以用 <code>hr</code> 标签来创建一条宽度撑满父元素的水平线。它一般用来表示文档主题的改变，在视觉上将文档分隔成几个部分。
|
||
</section>
|
||
|
||
## Instructions
|
||
<section id='instructions'>
|
||
在包含卡片标题的 <code>h4</code> 下面添加一个 <code>hr</code> 标签。
|
||
<strong>注意</strong><br>在 HTML 里，<code>hr</code> 是自关闭标签，所以不需要一个单独的关闭标签。
|
||
</section>
|

|
||
## Tests
|
||
<section id='tests'>
|
||
|
||
```yml
|
||
tests:
|
||
- text: '你应该添加一个 <code>hr</code> 标签。'
|
||
testString: assert($('hr').length == 1);
|
||
- text: '<code>hr</code> 标签应该在标题和段落之间。'
|
||
testString: assert(code.match(/<\/h4>\s*?<hr(>|\s*?\/>)\s*?<p>/gi));
|
