make div float up
<p>I am trying to make a chat option for users however I only want the chat to show for a certain amount of time, I could do this via PHP and timestamp but I would also like to visually hide it by making the div containing the message to float up until it becomes hidden as an overflow..</p>

<p>I seen a script on the following page:
<a href="http://rainbow.arch.scriptmania.com/scripts/bg/float_up.html" rel="nofollow">http://rainbow.arch.scriptmania.com/scripts/bg/float_up.html</a>
It uses images but I'd like to do the same idea with submitted messages (floating chat)</p>

<p>Any help would be appreciated</p>
