9 @media all and (min- 0px){
10 }
11 然后写
12 @media screen and (-webkit-min-device-pixel-ratio:0){}
一、添加在属性上
* ie6,ie7识别，ff不识别
_ ie6识别，ie>7,ff不识别
# ie 识别
eg: .selector{*background:url(image.jpg)}
.selector{_background:url(image.jpg)}
.selector{#background:url(image.jpg)}
二、添加在属性值上
！important ie>7, ff 识别
.selector{background:url(image.jpg)!important}
三、添加在选择器上
四、添加在全局
HTML: 添加body class:
<!--[if IE6]--><body class="ie6"><![endif]-->
<!--[if IE7]--><body class="ie7"><![endif]-->
<!--[if IE8]--><body class="ie8"><![endif]-->
<!--[if IE9]--><body class="ie9"><![endif]-->
<!--[if !IE]--><body class="non-ie"><![endif]-->
.sofish{padding:10px;}
.non-ie .sofish{padding:12px;}
.ie9 .sofish{padding:9px;}
.ie8 .sofish{padding:8px;}
.ie7 .sofish{padding:7px;}
.ie6 .sofish{padding:6px;}
/* webkit and opera */
@media all and (min- 0px){ .sofish{padding:11px;} }
/* webkit */
@media screen and (-webkit-min-device-pixel-ratio:0){ .sofish{padding:11px;} }
/* opera */
@media all and (-webkit-min-device-pixel-ratio:10000), not all and (-webkit-min-device-pixel-ratio:0) { .sofish{padding:11px;} }
/* firefox * /
@-moz-document url-prefix(){ .sofish{padding:11px;}} /* all firefox */
html>/**/body .sofish, x:-moz-any-link, x:default { padding:11px; } /* newest firefox */
[/css]
<p>然后，从第二种方式我们也可以发现。把IE注释用在body class上，而不是添加单独的<code><link /></code>或者<code>@import</code>会是更好的选择。虽然分文件也是一种不错的选择，但了为页面加载速度，HTTP请求一 个都不能浪费。</p>
<p>至于利用JS或者后端程序来判断，除非你有足够的资源，除非你解决不了（90%不会发生），不然，并不推荐用。附上一个表 （<a rel="nofollow" href="http://paulirish.com/2009/browser-specific-css-hacks/">via</a>），可以参考参 考：</p>
