Rollover Text in iWeb???

I am semi new to iWeb and want to enhance my current site. This is a brewery site, so what I am wanting to do is have a list of our brews, when someone mouses over the text of a brew style, a text box pops up at the bottom of the page with that brews description?? Is that possible??

We will have six brews on one page, these are listed at the top and i want the text to pop up at the bottom of each brew they rollover.

Example:

IPA

Red Ale

Harvest Ale

now one they mouse over these at the top i want descriptive text to pop up below

Also, can you add image and text in a single rollover??

Thanks so much
