Two ways to introduce CSS
1. Import through the @import directive
@import directive is part of the CSS language. When using it, add this directive to a c9ccee2e6ea535a969eb3f532ad9fe89 tag in HTML;
<style type="text/css"> @import url(css/styles.css); </style>
2. Introduction through tags (the most common way)
<link type="text/css" href="style.css" rel="stylesheet" />
The difference between the two methods
tag belongs to the html tag, and @import is a tag provided by css In this way, tags can not only introduce css, but also do other things, while @import can only introduce css
The difference in loading order: when a page is browsed, the css introduced by link will be loaded synchronously, and the css referenced by @import will not be loaded until all other elements have been downloaded;
Difference in compatibility: @import was only proposed in CSS2.1 , so it is only supported in IE5 and above, and lower version browsers do not support it, but tags do not have this problem;
When using javascript to control the DOM to change the style, only tags can be used. Because @import is not controllable by DOM.
