site is good in IE but not in firefox...

I just finished a web site and it looks great when i view it in internet explorer but when it's viewed in firefox, the site is all messed up. The homepage in firefox has only a minor flaw but when you view the other pages the bottom of the pages gets messed up with writing extending past the footer and other problems. Is there a way to fix the site so it looks good in firefox and stays looking good in explorer? The web site is ocontohousingauthority.com

Thanks!!!

and I did run the site through the w3 validator with only a minor tag error from one link.

Also, you might like to look into clearfixing. Here's a good post on Stack Overflow explaining the different ways to clear floats.

You might also find this Mozilla article about CSS floats interesting as well.

I hope that helps!

Thanks! I also figured out that my internet explorer was an old version so the site looked good even though it wasn't. I think i got the code worked out now.
