localeTitle: 使用hr元素创建水平线
---

## Description
<section id="description">您可以使用<code>hr</code>标记在其包含元素的宽度上添加水平线。这可用于定义主题更改或直观地分隔内容组。 </section>

## Instructions
<section id="instructions">在<code>h4</code>下面添加一个<code>hr</code>标签，其中包含卡片标题。 <strong>注意</strong> <br>在HTML中， <code>hr</code>是一个自动关闭标记，因此不需要单独的结束标记。 </section>

## Tests
<section id='tests'>

```yml
tests:
  - text: 您的代码应该在标记中添加<code>hr</code>标记。
    testString: 'assert($("hr").length == 1, "Your code should add an <code>hr</code> tag to the markup.");'
  - text: <code>hr</code>标签应位于标题和段落之间。
    testString: 'assert(code.match(/<\/h4>\s*?<hr(>|\s*?\/>)\s*?<p>/gi), "The <code>hr</code> tag should come between the title and the paragraph.");'
