Description

下一个添加语义含义并提高可访问性的HTML5元素是header标记。它用于为其父标记包装介绍性信息或导航链接，并且可以很好地处理在多个页面顶部重复的内容。 header分享了您在main看到的嵌入式地标功能，允许辅助技术快速导航到该内容。注意
header适用于HTML文档的body标记。这与head元素不同， head元素包含页面标题，元信息等。

Instructions

Camper Cat正在撰写一些关于忍者训练的精彩文章，并希望为他们的网站添加一个页面。将当前包含h1的顶部div更改为header标记。

Tests

tests:
  - text: 您的代码应该有一个<code>header</code>标记。
    testString: 'assert($("header").length == 1, "Your code should have one <code>header</code> tag.");'
  - text: 您的<code>header</code>标记应该环绕<code>h1</code> 。
    testString: 'assert($("header").children("h1").length == 1, "Your <code>header</code> tags should wrap around the <code>h1</code>.");'
  - text: 您的代码不应包含任何<code>div</code>标记。
    testString: 'assert($("div").length == 0, "Your code should not have any <code>div</code> tags.");'
  - text: 确保您的<code>header</code>元素具有结束标记。
    testString: 'assert(code.match(/<\/header>/g) && code.match(/<\/header>/g).length === code.match(/<header>/g).length, "Make sure your <code>header</code> element has a closing tag.");'
