  1.   

    一个例子
    <STYLE>
       INPUT.aFilter {filter:Alpha(opacity=50);}
    </STYLE>
    <INPUT TYPE="button" VALUE="Button" CLASS="aFilter">
      

  2.   

    Alpha 滤镜
    语法：{Filter:alpha(opacity=opacity,finishopacity=finishiopaciry,style=style,startx=startx,starty=starty,finishx=finishx,finisshy=finishy)}
      

  3.   

    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
    <script>
    var ww
    var i=0
    var flag="1"
    function test(){
    if(i>99)
    i=0
    i+=5
    document.all.mxh.style.filter="alpha(opacity="+i+")"
    ww=setTimeout("test()",10)
    }
    </script>
    </head><body bgcolor="#FFFFFF" text="#000000">把你的鼠标移动到图片上<br>
    <img id=mxh src="http://lucky.myrice.com/back.jpg" style="filter:alpha(opacity=50)" onmouseover="test()" onmouseout="clearTimeout(ww)"> 
    </body>
    </html>
