## Description
|
|||
|
|
<section id="description">下一个添加语义含义并提高可访问性的HTML5元素是<code>header</code>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。 <code>header</code>分享了您在<code>main</code>看到的嵌入式地标功能，允许辅助技术快速导航到该内容。 <strong>注意</strong> <br> <code>header</code>适用于HTML文档的<code>body</code>标记。这与<code>head</code>元素不同， <code>head</code>元素包含页面标题，元信息等。 </section>
