谈谈随滚动条始终不动的div

不管滚动条怎么拉，div始终相对屏幕位置不变，就像网易空间右下角的那种，一点都不卡，请高手指导指导。

<div style="background: none repeat scroll 0% 0% Red; width: 100px; height: 100px; bottom: 10px; right: 10px; position: fixed;"></div>
关键的样式：xxx{bottom:10px;right:10px;position:fixed;}
ie6还要看这个

LZ看看这个例子<html>
<head>
<script language = "javascript">
    var checks = 0;
    var GB =0;
    function openwindow()
    {
     checks = document.getElementById("player").style.pixelTop;
     GB = document.getElementById("myplay").style.pixelTop;
    }
function move()
{
document.getElementById("player").style.pixelTop = checks + document.body.scrollTop;
document.getElementById("myplay").style.pixelTop = GB + document.body.scrollTop;
}
function guna()
{
document.getElementById("myplay").style.display = "none";
document.getElementById("player").style.display = "none";
}
window.onscroll = move;
</script>
</head>
<body onload = "openwindow()">
<div id = "play" style = "position:absolute;height:2000px;width:990px;background-color:orange;z-index:1"></div>
<div id = "player" style = "position:absolute;height:100px;width:100px;left:900px;top:100px;background-color:blue;z-index:2"></div>
<div id = "myplay" style = "position:absolute;heigth:20px;width:40px;left:970px;top:80px;z-index:3" onclick = "guna()"><font size = 3 color = red><a href = "#">关闭</a></font></div>
</body>
</html>
postion:fixed  只可惜IE6不支持
用固定定位 IE：用那个经典的模拟固定定位的CSS  （纯CSS就可实现）
