帮顶
[解决办法]
使用背景图片

http://faq.csdn.net/ui/styles/index/bgContentPanelCaption.gif
[解决办法]
不如干脆做个会动的gif图片算了~~~也不用去移坐标了~~
[解决办法]
不过....gif动画做背景貌似不会动....
[解决办法]
先飘过的说。。。
写过。。不过code不美观给kill了。。
[解决办法]
我回来了。。忽忽。。
写了一个。。因为是用1个timeout执行的所以判断多了些。。
另外out的时候。。颜色变化速度也没有设置，还是和over的时候速度一样。。所以效果不是很PL忽忽。。去做东西了。。
用空在改下out。。
Code先贴上。。。

[解决办法]
这个效果是我写的。一个 highlight 效果，鼠标 over 的时候换深色， out 的时候换回原来的颜色，只不过在换深色/浅色的时候有一个渐进过程罢了。
[解决办法]
哈哈。。梅老师中午好，梅老师辛苦了。嘿嘿。。
我又重新把这个特效写了一变。。。。
不过这次比上次写的麻烦了好多。。但比上次的那个稳定了。。

想实现一个类似于CSDN -gt; FAQ列表页的
