纯DIV/CSS对联漂浮广告代码(无JS)

源码网两侧漂浮。经测试，兼容IE6，IE7，Firefox浏览器。

CSS代码为：
.r1{width:80px;height:80px;background:red;float:right;  
     position:fixed !important; top/**/:200px;  
     position:absolute; z-index:300; top:expression(offsetParent.scrollTop+200);right:20px;}
.r2{width:80px;height:80px;background:red;float:right;  
     position:fixed !important; top/**/:300px;  
     position:absolute; z-index:400; top:expression(offsetParent.scrollTop+300);right:20px;}
.l1{width:80px;height:80px;background:red;float:right;  
     position:fixed !important; top/**/:200px;  
     position:absolute; z-index:300; top:expression(offsetParent.scrollTop+200);left:20px;}
.l2{width:80px;height:80px;background:red;float:right;  
     position:fixed !important; top/**/:300px;  
     position:absolute; z-index:400; top:expression(offsetParent.scrollTop+300);left:20px;}
