<body>
<div  style=" float:left;">
   <img  src="img/w_dongmanyouxi.jpg" alt="韩庚"/>
    <span class="Divspan" style=" position:relative;">韩庚韩庚韩庚韩庚韩庚</span>
</div>
</body>
</html>

重点：将元素设置成透明，其子元素不会透明CSS

background: none repeat scroll 0 0 rgba(22,123,235,0.5);
filter: progid:DXImageTransform.Microsoft.gradient(startcolorstr=#7F167BEB,endcolorstr=#7F167BEB);
