Keep footer at bottom of content

I don't know for sure but here's a couple of places to figure it out. The sticky footer seems to be a major problem for a lot of people.

I like css-tricks for other things but haven't tried the sticky footer.

By the way, unless your doing it intentionally, you can think of your separate files and the way they look to the browser when they all load in the page as a single html output. In other words you can put this css in one style.css and link it to your header part rather than putting style tags in each file.
