  2    
  3  仅 Firefox 3 和 IE7 识别的 Hack:  
  4  selector, x:-moz-any-link, x:default \{  
  5  /\* Firefox 3  and IE7 rules here \*/  
  6  \}  
  7    
  8  如果想区分opera和safari的话先写  
  9  @media all and (min-width: 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:

< [body][] class="ie6"><!\[endif\]-->    
< [body][] class="ie7"><!\[endif\]-->    
< [body][] class="ie8"><!\[endif\]-->    
< [body][] class="ie9"><!\[endif\]-->

<[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-width: 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>
