大家帮帮我吧！！！！
我的系统安装的是IE5.0，在我的电脑中做的网页字体和表格是用css定义的，这些css样式在我的电脑中的浏览器能够正常显示，可是在IE6.0的浏览器中却不能正常显示，这是为什么啊？是不是IE6.0不支持CSS样式？？？？

ie5支持ie6怎么会不支持。不知道你的css代码是什么？给个地址look一下？

微软做的东西，一向都是兼容性强，一般新版本对老版本的东西是能够很好支持的，
所以当遇到这样一些问题的时候不要把头脑用在微软的软件问题上，而应该再仔细去分析一下自己写的东西，看看错误在哪里！

哈，我找到一个初步原因，是IE6不支持命名过长的CSS文件，IE6的兼容性还不如IE5。

是吗？如何知道的？最长支持多长？
