Hi, I've recently begun working on my own Twenty Eleven child theme, and can't seem to figure out how to remove the default gray background that surrounds my site. Is this border its own element, or a border for some other element? Any help would be much appreciated. I'm most concerned with removing the border from the top and bottom, but would like to be able to change the sides as well.
