Firefox/IE上无法使用CSS样式

Question

我设计了一个使用Dreamviewer的网站。我应用于网页的样式在Firefox和IE上不可用，网页以纯HTML格式显示。但所有样式都可以在Chrome中很好地显示。究其原因，以及如何解决该问题？

这是我的样式表

我看不出有任何先进的或复杂的CSS代码，因此所有的现代浏览器都支持它。总之，这里是一个清单：

清单

• 你有没有检查不同的浏览器版本（你可以旧版本之间的Internet Explorer中切换）？检查：http://msdn.microsoft.com/en-us/library/gg699485(v=vs.85).aspx
• 你试过更简化的CSS吗？
• 您是否清理了浏览器缓存？
• 您是否尝试过“浏览器嗅探”？检查：http://en.wikipedia.org/wiki/Browser_sniffing
• 你在另一台电脑上试过吗？

如果你在线测试，你可能想检查你的.htaccess。
