Background Color issue

[clayton47]

I have created a containing div and applied a background color of white. When i turn off template names in the admin cp it doesnt wrap all the contents like it does when the "show template names" is enabled. Can anyone look and see whats wrong? texasmx.com/forums the home page of the cms is where the issue is. the forum works except when viewing a thread. but the general thread display views normal. I would really appreciate it.
