<div iclass="divTest">
<div class="divChild"></div>
<img src="demo_files/sago.jpg" width="300" height="200" class="childImg" />
</div>
.divTest{width:300px;height:200px;position:relative;}
.divChild{width:300px;height:200px;position: absolute;top:0px;left:0px;filter:alpha(opacity=50);opacity:0.5;background-color:white; z-index:100;}
.childImg{top:0px;left:0px;position:absolute;z-index:1;}
请问为什么在IE6下没有透明的效果
需要设置filter效果
