Div background not showing

hi, I just started a site and I’m having some trouble. I’m new to css here.

I’m using dreamweaver and adding div tags to the page. I can preview my page in any browser via dreamweaver CS3 and the background of the div tags work properly, but when I tried to test it online the backgrounds don’t show in any browser.

It’s div tag id “band” and “footer” at the bottom. They are just two tags w/ two different repeating background patterns. (I have yet to clean up the html. I’m going to do that later. )
I’ve read something about floating the div tag?!? [URL=“http://www.crystalgraphix.net/carylonkillebrew”]
