Layout consists of five max-width columns and they adapt to the size of the screen. When column is clicked the fullscreen is applied. I decided to modify Mary Lou "Fullscreen layout with page transitions" tutorial which you can find here here: http://tympanus.net/codrops/2013/04/23/fullscreen-layout-with-page-transitions I only changed the columns size parameters.
