You set the width and height of the divs inside the style tag, you only have to
change the divCont, Remeber to set the clip the same as the width and height.
You can remove the divUp and divDown layers if you want. 
This script should also work if you make the divCont position:relative.
Then you should be able to place this inside a table or something. Just remember
that Netscape crash very easily with relative positioned divs and tables.

Updated with a fix for error if moving over layer before pageload.
