Padding Troubleshooting

I just changed the background color of our blog

http://kermitlynch.com/blog/

And I’m having problems adding more white padding onto each side of the blog, just to give a little more space between the text and the gray background color. I’ve messed with the padding but I’m not even sure if that’s how to fix it. Anyone have any suggestions?

Thanks,
Ryan
