I have been hearing more and more about CSS frameworks that use grids, but I didn’t really get what they were talking about until reading Jason Santa Maria article over at 24ways.org: Making Modular Layout Systems. Now I have a better idea of why people are so buzzed about trying to get something like 960 Grid or BluetripCSS into Drupal 7 as a core theme (http://groups.drupal.org/node/16457)
