/* The 12-column Deco Grid System. 
 * Available in multiple variants, see http://deco.gs
 *
 * Cells are   6.25%    (=60px)
 * Margins are 1.04166% (=10px) (times two, left and right)
 * Total is    8.33333%. (=80px) (which makes 12 columns)
 * 
 * If page width is fixed to 960px width:
 * Cell will be equivalent to 60px, left/right margin will be 10px.
