CSS pseudo-classes are used to add special effects to some selectors.
CSS伪类可用来给一些选择器加上特殊效果。
Hyperlink
如何在文档内给超级连接加上不同的颜色
This example demonstrates how to add different colors to a hyperlink in a document.
Examples 实例：

 代码如下 复制代码

a:link {color: #FF0000}
a:visited {color: #00FF00}
a:hover {color: #FF00FF}
a:active {color: #0000FF}
This is a link
Note: a:hover MUST come after a:link and a:visited in the CSS definition in order to be effective!!
