.back-to { bottom: 35px; overflow: hidden; position: fixed; right: 10px; width: 110px; z-index: 999;}.back-to .back-top { background: url("back-top.png") no-repeat scroll 0 0 transparent; display: block; float: right; height: 50px; margin-left: 10px; outline: 0 none; text-indent: -9999em; width: 50px;}.back-to .back-top:hover { background-position: -50px 0} 在IE6下显示错位，与IE8的现实位置不一样！求教解决代码，谢谢大家了
