Golden Grid System

Golden Grid System, a folding grid for responsive design. I’m not big on frameworks, especially when we’re talking about baseline grids, but this one is really well done. And I can get behind this sentiment from its creator: “Take it apart, steal the parts that you like, and adapt them to your own way of working.” Plus it’s a beautiful design to boot. Be sure to resize your browser a lot and play with the little grid reveal button on the top right of the page.
