Flexible, efficient layout.
You've probably used a grid framework before — we think you'll like this one. It's a 12-column flexible grid that can scale out to an arbitrary size (defined by the max-width of the row) that's also easily nested, so you can build out complicated layouts without creating a lot of custom elements. And when the Grid isn't enough for your site, it just gets out of the way.
