我在CSS文件中定义 MENU的背景
#top_containter #menu {text-indent:10px;line-height:25px;font-size:14px;color:#FFFFFF;text-align:left;width:960px;background:#d20a26}
在IE下是正常的,但是在FF下背景为什么老是不起作用呢??????
------解决方案--------------------
没问题，完全可以显示。以下是我用你的代码做的，在FF中可以显示背景颜色，与IE浏览器相同。
<html xmlns="http://www.w3.org/1999/xhtml" >
<head><title>
</title>
<style type="text/css">
#top_containter #menu {text-indent:10px;line-height:25px;font-size:14px;color:#FFFFFF;text-align:left;width:960px;background:#d20a26}
</style>
</head>
