rwdgrid

rwdgrid is a basic grid system coded in CSS that will help developers create responsive HTML pages.

Don't let yourself be fooled. Grid systems may be a dime a dozen, but that's because most of them are quite useless, don't follow general conventions, or aren't thoroughly tested.

Few actually have insightful class names, provide pull & push classes, come with mobile support, or even provide documentation.

rwdgrid not only does it provide a demo and a basic PSD file for designing future projects on it, but also follows general naming conventions established by tools like the 960GS and HTML5 Boilerplate.

It has also been tested on all modern browsers, plus a slew of mobile devices.
