When viewing the course description page, all of the 2.5 themes (except Afterburner) shift the description to the right 1/2 of the description block, thereby creating a whole lot of wasted space and the description ends up being twice as long as it needs to be. Too much whitespace results from the shifting of the course description to the right of the course title.
