## Description

|
|
<section id="description"> HTML5引入了更具描述性的HTML标记。这些包括<code>header</code> ， <code>footer</code> ， <code>nav</code> ， <code>video</code> ， <code>article</code> ， <code>section</code>和其他。这些标签使您的HTML更易于阅读，并且还有助于搜索引擎优化（SEO）和可访问性。 <code>main</code> HTML5标记可帮助搜索引擎和其他开发人员找到您网页的主要内容。 <strong>注意</strong> <br> “应用可访问性”部分介绍了许多新的HTML5标记及其优点。 </section>
