实现标题栏鼠标滑过点击过后保持原色，不用像你那样写得这么复杂，按照你说的，只需要写一次样式就够了，写法如下： #dh ul li a { display:blockbackground:#006eadwidth:125pxheight:43px} 现在我无论是在默认状态下、鼠标移上去时、鼠标点击时，或是点击过后，a标签背景颜色都会保持在初始状态，不会改变。如果需要鼠标移上去时，背景变色，那就加多一条a:hover，写法如下： #dh ul li a:hover{ display:blockbackground:#0193dewidth:125pxheight:43px} 现在就只有鼠标移上去时背景会变色，其他情况颜色都不会变化。提示：如果需要文字一直保持原色，只需要在第一条#dh ul li a 的代码里加上一条“color:颜色属性”即可。例如：#dh ul li a {background:#006eadcolor:#fff} 试一试吧！

单纯用css肯定不能实现这种效果，需要用到jQuery，代码如下：

然后再用css去修改样式就好。
