Continuation from CSS footer from cssstickyfooter.com not working correctly
This footer from http://www.cssstickyfooter.com/ isn't reaching the edges of the Browser's window:
The footer should be "touching" the right and left sides of the window, but as you can see, there seems to be a small margin. Honestly, I'm not sure how to start fixing this. But I don't think it's a bug because it renders the same way in Chrome, Firefox, and I think even in Internet Explorer.

Add to your code
html, body { padding: 0; margin: 0; }
to prevent spaces around your footer
