#bg{width:100%;height:100%;top:0px;left:0px;position:absolute;filter: Alpha(opacity=50);opacity:0.5; background:#000000; display:none;}
#popbox{position:absolute;width:300px; height:200px; left:50%; top:50%; margin:-200px 0 0 -200px; display:none; background:#FFFFFF;}
</style>
<body>
终于搞定这个效果了，IE和FF,OP均可以~
先说原理:两个层,一个高度和宽度都是100%,另一个就是你要弹出的窗口的具体内容,半透明在IE中是用filter: Alpha(opacity=60);在非IE中用opacity:0.60;

<div id="bg"></div>
<div id="popbox"><center style="margin-top:70px;"><img src="<ww:url value=‘/image/correct.jpg‘/>" /> <span id="msg"></span></center>
<br/><br/><br/>
<img src="<ww:url value=‘/image/ok.png‘/>" width="70" height="35" onclick="pupclose()" style="cursor:pointer"/>
</div>
</body>
