HTML (Hypertext Markup Language) is a markup language used to build web pages. It is the basis for building web pages. In this article, we'll cover how to write HTML and add style and functionality to your website.

1. Writing HTML documents

HTML documents are composed of tags, and tags can be nested. Each tag has an opening tag and a closing tag, for example:

   
  
欢迎来到我的网站
 
这是一个段落
  

In this example, we have a root tag of HTML, atag that contains the title of the web page, and a the ; tag contains the content of web page. within tag, we have an >

tag for the heading and a
