HTML标签

HTML标签就像关键字一样，定义了Web浏览器如何格式化和显示内容。借助标签，Web浏览器可以区分HTML内容和简单内容。 HTML标签包含三个主要部分：开始标签，内容和结束标签。但是某些HTML标记是未封闭的标记。

当网络浏览器读取HTML文档时，浏览器从上到下以及从左到右读取。 HTML标记用于创建HTML文档并呈现其属性。每个HTML标签都有不同的属性。

HTML文件必须具有一些基本标记，以便Web浏览器可以区分简单文本和HTML文本。您可以根据代码要求使用任意数量的标签。

  • 所有HTML标记必须包含在这些括号内。
  • HTML中的每个标签执行不同的任务。
  • 如果您使用了开放标签，则必须使用封闭标签(某些标签除外)
