<link>和@import url()引入外部css文件的区别_html/css_WEB-ITnose

和@import url()引入外部css文件的区别:
标题中的两种方式都可以引入外部css文件,关于它们的基本用法这里就不多介绍了,具体可以参阅相关阅读。相关阅读:
(1).标签可以参阅HTML的标签一章节。
(2).@import url()可以参阅css的@import url用法简单介绍一章节。
下面介绍一下这两者的比较明显的区别。
(1).加载机制不同,link方式是首先加载完css文件,然后再加载页面,而@import url()是先加载玩页面,再加载css文件。
(2).支持IE5,@import url()不支持IE5,不过这一条好像现在根本不用考虑,IE8已经都快没了。
(3).js可以通过dom方式控制link,但是不能够控制@import url()方式。
(4).由于性能等各方面原因,不推荐使用@import url()方式。
