i have a website and i have multiple css style sheet for print, tv, screen, handheld etc...

我想知道这些方法（性能，可用性...）

i want to know which one of these method is better to use (performance, usability, etc...)

<link href="all.css" media="all" type="text/css" />
<link href="handheld.css" media="handheld" type="text/css" />

<style type="text/css">
    @import url("all.css") all;

    @import url("tv_print.css") tv, print;
</style>

推荐答案

第一种方法（链接）是最好的。

The first method (link) is the best.

主要原因是IE 6,7和8中有一个错误大约9或更高）意味着当您使用@import与链接时，文件是串行加载而不是并行加载。当使用多个样式表时，这可以减缓很多事情。

The main reason is that there is a bug in IE 6,7 and 8 (not sure about 9 or higher) means that when you use @import in conjunction with link the files are loading in series rather than in parallel. This can slow things down a lot when using more than one style sheet.

只是使用@import下载系列，但是顺序是不能保证的，

Just using @import downloads in series, but the order isn't guaranteed, meaning that if there is a reset for instance, that may or may not be applied first.
