<div id="Layer1" style="position:absolute; left:expression(window.screen.width-163); top:expression(window.screen.height-147); width:163px; height:147px; z-index:1">hhhh</div>
<div id="Layer1" style="position:absolute; left:expression(window.screen.width-163); top:expression(window.screen.height-147); width:163px; height:147px; z-index:1">hhhh</div>

</div><script>
var obj = document.getElementById("Layer1");
obj.style.left=window.screen.width-163;
obj.style.top=window.screen.height-147;
</script>大致可以如此把,自己改改。
