无论我尝试做什么，我都无法修改链接的颜色（希望创建颜色翻转效果）。它们总是保持与下划线效果相同的默认蓝色。我知道我做错了很小的事，但是谁能告诉我？不修改链接属性的CSS

新编辑09/27：
所有。我很抱歉发布两次 - 我是全新的，并没有想到继续在这个线程。正如我的帖子所示（请参阅Sparky672的链接），我的列和导航出现问题，看起来我是如何需要的。请参阅此链接进行演示http://rich2233.host22.com/pold.html ..我想你可以从浏览器中获取代码。感谢您的帮助
你错过了一些我通过编辑你的问题来解决它们的大括号。你的代码中的另一个问题是，应该按照特殊顺序为'A'创建css，我在下面的答案中提供它。干杯。 –
@Javad_Amiry，你不应该编辑OP的代码，以消除报告问题的可能原因。这使得问题和所有答案（除了你的）都不相关。我把它翻了回来。 – Sparky
