Post background is wide after 1st post

I was making a few changes in my style sheet and I realized that the background after the first post on my blog is as wide as the screen. I use firefox, and I also checked this in IE, it is showing up in both browsers.

I tried to retrace my steps and undo whatever I did, but no luck. Any help or suggestions would be greatly appreciated!
