There are three main ways to use CSS in the page: adding and defining style attribute values ​​​​inline, inline calls in the page header and external link calls. There are two types of external references: link and @import. The two ways of externally referencing CSS, link and @import, are:

link code

<link rel="stylesheet" rev="stylesheet" href="CSS文件" type="text/css" media="all" />

@import code

<style type="text/css" media="screen">  
@import url("CSS文件");   
</style>
