Comment background.

Good afternoon Sakin, I'm just about done with my customization of your extremely flexible theme.  I hit a bit of a brick wall with the background of the comments (once posted) and the comment entry themselves. My plan is to put a border around the comment entry and change the background to black so that the fonts are more visible, but I cannot find where to change the backgrounds for neither the posted comment nor the comment entry. Any advice would be greatly appreciated. Thanks, Piirus Oh, here is the URL http://blog.plagueoftheblackheart.com/?p=342.
