Making my page compatible with older IE

Hello there!

I am currently busy making a page for someone. It’s starting to look promising. I am currently in the process of making a Theme. So far it’s going well. The theme is looking great on Chrome, FireFox, and IE8 but when I turn on compatibility mode on IE8, the layout totally gets scrambled. I’ve built and tested the theme on Chrome so I didn’t know I was doing something wrong for IE6 and IE7.

I’ve searched on google and found that it has something to do with the float elements in my CSS but I couldn’t find a solution i could understand. As I have a LOT of float elements, I have a lot to fix. Does anyone know what the solution to this problem is?
