Theme Horse

I placed the content from the bottom footer into the four columns and changed the background so that works. But I would need to reduce the height of the columns to 80px (just like the top navigation bar)

I tried the .widget-wrapper but this does not work. When I set #colophon .one-fourth to a width of say 80 px, it does some strange things and place the last column in the first spot.

any ideas how i can reduce the height of the colophon footer?
