Answer 2

我不知道这是不是你想要的，但尝试：

-webkit-appearance:none; 

Answer 3

你需要使用jQuery

if($.browser.chrome){ 
userAgent = userAgent.substring(userAgent.indexOf('chrome/') +7); 
userAgent = userAgent.substring(0,userAgent.indexOf('.')); 
version = userAgent; 
    // If it is chrome then jQuery thinks it's safari so we have to tell it it isn't 
$.browser.safari = false; 
     } 

那么你可以申请在你的CSS多次更改这些诸如背景来检测浏览器：通过指定，如果没有这是铬或不。

background-color:#ffffff; 
background-image:-webkit-gradient(linear, left bottom, left top, color-stop(0,    #f4f4f4), color-stop(0.48, #eeeeee), color-stop(0.5, #f6f6f6), color-stop(0.8, #ffffff)); 
background-image:-webkit-linear-gradient(center bottom, #f4f4f4 0%, #eeeeee 48%, #f6f6f6 50%, #ffffff 80%); 
background-image:-moz-linear-gradient(center bottom, #f4f4f4 0%, #eeeeee 48%, #f6f6f6 50%, #ffffff 80%); 
background-image:-o-linear-gradient(top, #f4f4f4 0%, #eeeeee 48%, #f6f6f6 50%, #ffffff 80%); 
background-image:-ms-linear-gradient(top, #f4f4f4 0%, #eeeeee 48%, #f6f6f6 50%, #ffffff 80%); 
background-image:linear-gradient(top, #f4f4f4 0%, #eeeeee 48%, #f6f6f6 50%, #ffffff 80%);
