关于CSS的层和类的圆角问题

Firefox下可以在.css文件的层中加入-moz-border-radius: *px; 实现圆角
在IE下该怎么解决呢呢? 除了用图片代替.

 

木人告诉我
我自己解决
不告诉你们答案

 

代码:

<style type="text/css">

#xsnazzy h1, #xsnazzy h2, #xsnazzy p {margin:0 10px; letter-spacing:1px;}
#xsnazzy h1 {font-size:2.5em; color:#fff;}
#xsnazzy h2 {font-size:2em;color:#06a; border:0;}
#xsnazzy p {padding-bottom:0.5em;}
#xsnazzy h2 {padding-top:0.5em;}
#xsnazzy {background: transparent; margin:1em;}

.xtop, .xbottom {display:block; background:transparent; font-size:1px;}
.xb1, .xb2, .xb3, .xb4 {display:block; overflow:hidden;}
.xb1, .xb2, .xb3 {height:1px;}
.xb2, .xb3, .xb4 {background:#d4d4d4; border-left:1px solid #08c; border-right:1px solid #08c;}
.xb1 {margin:0 5px; background:#08c;}
.xb2 {margin:0 3px; border-width:0 2px;}
.xb3 {margin:0 2px;}
.xb4 {height:2px; margin:0 1px;}

.xboxcontent {display:block; background:#d4d4d4; border:0 solid #08c; border-width:0 1px;}


</style>

代码:

<div id="xsnazzy">
<b class="xtop"><b class="xb1"></b><b class="xb2"></b><b class="xb3"></b><b class="xb4"></b></b>
<div class="xboxcontent">
