把如下代码复制到<body></body>之间

<DIV id="fadeinbox" style="filter:progid:DXImageTransform.Microsoft.RandomDissolve(duration=1) progid:DXImageTransform.Microsoft.Shadow(color=gray,direction=135) ; -moz-opacity:0"> 欢迎来到网页特效库网页网页特效,希望在这里能找到你需要的东西<br> 收集最好最实用的特效，让你的工作更简单 <br> <div align="right"> <a href="#" onClick="hidefadebox();return false">隐藏</a> <div> </DIV>
