bwilsonnet on "Footer changed/won't keep dimension in newly created custom page"

I created two new custom pages so that I could get rid of the sidebar and extend the post/content section of the page.

When I did that I noticed the footer stretches outside of the boundaries of the page, and differs from the main page.

I've scoured the internet for a solution and tried some things, but nothings worked. I know just enough about html/php to get me by.

Any suggestions would be appreciated.
Here's the two pages.

If you notice on my about page if I don't extend the content it doesn't do that even though I've removed the sidebar (testing different codes), and it's perfectly fine on the index page. I thought it might be something with the css, but I haven't a clue in regards to that stuff.

Thanks again for any help!
