Buffered shrink and expand content effects_navigation menu

Compatible with ie5.5 and firefox2.0 (because I only have these two browsers, I only tested them in them)

I saw that many friends from blueidea have posted some effects of shrinking and expanding content. The only difference is It is a buffering effect. Not much to say, you will know after running it, haha.
The maximum height also needs a fixed value. There is no good solution. Friends who are interested can help solve it, thank you.
This Other parts of the code will not be released after updates and improvements. If you need to encapsulate it, just do it yourself, haha.

The code is released for sharing and learning. Please respect other people's works and do not use them for commercial purposes!! !!!

Copy code The code is as follows:
