Hey guys.

I need some help in a bad way. I need to put a floating banner on a page that is CSS to call attention to a "sale". I don't really know CSS, this is all new to me but I am trying to help out a friend who has done a lot for me.

The sites I am working on are:

Code:
http://www.american-emergency-products.com
Code:
http://www.auto-additions.com
On both of those pages, I need to put a floating banner, kind of like the "SUBSCRIBE" callout on this page:
Code:
http://www.webresourcesdepot.com/smart-floating-banners/
or the deal in the bottom right corner on this page:
Code:
http://demo.joomlashine.com/joomla-templates/jsn_epic/pro/index.php
I know this must be easy, but everything I have tried thus-far has been unsuccessful. I am open to any ideas.

PLEASE HELP!! Thank you!
