Remove small white space at bottom of main content

I would like to remove the small white space at the very bottom of the main content — not the space between the main content and the footer (I already removed that), but the very small space at the bottom of the main content. I realize I could just change the background color of the whole page, but I don’t want to do that (for purposes of the mobile version and an app that I am making). Can someone help a brother out?
