<dl>
<dd><a href="#">产品一</a></dd>
<dd><a href="#">产品一</a></dd>
</dl>
</li>
</ul></body>
</html> 以上菜单在IE6上是无法显示的，大家帮忙看看改改！！谢谢
<a href="#" id="a">产品介绍</a>#nav li:hover dl{
display:block;
}
这个在IE6.0根本就无效不想改你的样式，你要在IE6下显示，脚本控制下就行了
<attach event="ondocumentready" handler="parseStylesheets" />

</script>上面比如命名csshover.htc
然后加入css 代码a{behavior:url("csshover.htc")}，这样ie6就支持了
