Twenty Ten theme – additional non-blog pages losing background color on sides?

Hi, first off let me state that I have searched the forums for hours for an answer and couldn’t find anything.

I am extremely new to CSS and PHP, but am able to fumble through with enough trial and error.

I am using the Twenty Ten Theme and 3.0.1 of WordPress.

Anyway, below are links to 2 screenshots:

The first is my BLOG page, which is functioning perfectly. The blog page uses the default template.

The second is a link to my ABOUT page. You can see how the white/grey background has not extended to match the width of the header, nor has it filled in the footer area. I have expanded the width of the .one-page content from 640 pixels to 900+, but that still obviously hasn’t fixed my problem.

There is also a few white/grey pixel padding beneath the header / above the menu which I can’t seem to get rid of.

The same thing happens on all of my non-blog pages, which all use the “One column, no sidebar” template.

Again, to reiterate, I am trying to match the look of all the pages to the BLOG page.

Can someone help me out here, thank you in advance,
