如何在样式表中区分不同的IE版本？如何使兼容IE8与IE10的滚动条颜色？

body
{
    vertical-align:top;
    background-color:#FFFFFF;
    margin:0px 0px 0px 0px;
    color:#000000;
    font-size:12px;
    font-family:Verdana, Arial, Helvetica, sans-serif;
    scrollbar-3dlight-color :#DEE7F8; 
    scrollbar-highlight-color :#DEE7F8; 
    scrollbar-face-color : #DEE7F8;
