Removing background behind userpics/userinfo on posts
I'm very much a beginner with this, but I dug around and really tried to find the answer to this question before resorting to posting. I haven't been able to find anything; I'm sorry if I've overlooked it.
My question is about removing the white block around the userpic/userinfo in people's posts on my friends pages. What do I need to add to my custom CSS to make it go away?
