Formatting Posts vs. Pages

Hello,

I’m a bit confused. I made some changes to what my posts look like but it affected what my pages look like as well and I can’t compensate so they both look the same. Specifically, there’s something going on that’s making my pages jut out on the right hand side, but not my posts. Please take a look at my main page:

http://www.thebattlenow.com/

and then the other page:

http://www.thebattlenow.com/index.php/about-2/

Where is the CSS line that can make my page look the same as my post?

Thanks for your help,

Thomas
