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.");'
