AJAX help

Er, i need some help. My website http://www.krawk.net is coded in ajax. However when a user clicks a button at the top of the page, i want the content to slowly change just like this site:

http://www.neopetstuff.net/

^ look how cool it goes when you click a button, it goes really smooth instead of my site. What is the code to do this?

 

http://www.neopetstuff.net/mootools.js
http://www.neopetstuff.net/script.js

 

Oh... Do both those js files have the code in em? How would I intergrate it on my site o.o?

 

Hi,

You must include the following line in html page:

<script type="text/javascript" src="./mootools.js"></script>
<script type="text/javascript" src="./script.js"></script>

Hope this will help you.
Thanks
