HTML head标签的作用是什么-开发者知识库平台

HTML head标签用于定义HTML文档的头部，其中包含了一些元数据（metadata），即提供关于HTML文档的信息，而不是显示在页面上的内容。具体作用如下：

设置文档的标题：使用标签中的标签来定义文档的标题，标题将显示在浏览器的标题栏或标签页上。</p> </li> <li> <p>引入外部资源：可以在<head>标签中使用<link>标签引入外部样式表（CSS文件），以及使用<script>标签引入外部JavaScript文件。</p> </li> <li> <p>定义字符集：可以使用<meta>标签定义文档的字符集编码，例如使用<meta charset="UTF-8">来指定文档使用UTF-8编码。</p> </li> <li> <p>设置视口：可以使用<meta>标签设置移动设备的视口，以确保页面在移动设备上正确显示。</p> </li> <li> <p>描述文档内容：可以使用<meta>标签的"description"属性来提供对文档内容的描述，这对于搜索引擎优化（SEO）非常有用。</p> </li> <li> <p>定义关键词：可以使用<meta>标签的"keywords"属性来定义文档的关键词，这也是用于SEO的一种方法。</p> </li> <li> <p>指定作者和版权信息：可以使用<meta>标签的"author"和"copyright"属性来指定文档的作者和版权信息。</p> </li> </ol> <p>总之，<head>标签是用来设置关于HTML文档的元数据和其他信息的地方，这些信息通常不直接显示在网页内容中，但对于网页的正确渲染和优化非常重要。</p> </p> <p class="adv-content"><a href="/" target="_blank">辰迅云<span>「云服务器」</span>，即开即用、新一代英特尔至强铂金CPU、三副本存储NVMe
