超文本标记语言（HyperText Markup Language，简称HTML）是一种用于创建网页的标准标记语言。HTML用于描述网页的结构和内容，使得网页可以在各种设备和浏览器上呈现和展示。HTML文档由一系列的标签（Tag）组成，这些标签用于定义网页中的不同元素，如标题、段落、链接、图像等。
HTML文档的基本结构包括以下几个部分：
1. ``：声明文档类型和版本。
2. ``：整个HTML文档的根元素。
3. ``：包含元数据和其他一些设置信息，如字符集声明、CSS样式表和JavaScript脚本等。
4. ``：定义网页的标题，显示在浏览器的标题栏或标签页上。
5. `<body>`：包含网页的可见内容，如文本、图像、列表等。
除了基本的结构标签外，HTML还包括许多其他的标签，用于定义各种网页元素和功能。例如，`<h1>`到`<h6>`标签用于定义标题的层次，`<p>`标签用于定义段落，`<a>`标签用于创建链接，`<img>`标签用于插入图像等。
HTML是构建网页的基础技术之一，与CSS（层叠样式表）和JavaScript一起，构成了网页开发的三大核心技术。通过HTML，可以创建网页的结构和内容；通过CSS，可以定义网页的样式和布局；通过JavaScript，可以实现网页的交互性和动态效果。
