Foundation is a rock-solid, responsive framework for rapidly prototyping and iterating into production code. It includes tons of great tools and elements that’ll get you up and running in no time.

Within global.css you’ll find The Grid, a layout framework that works on mobile devices, small screens and full-on modern desktops. It’s a twelve column, semi-liquid, mobile-scaling grid of awesomeness that you’re gonna love. It even supports arbitrary nesting.

Foundation includes dozens of styles and elements to help you quickly put together clickable prototypes, that can then be adapted and styled into polished production code. Forms, buttons, tabs, all kinds of good stuff. Foundation is MIT-licensed and absolutely free to use.

You should also look at Twitter Bootstrap Toolkit we mentioned earlier too. It includes base CSS and HTML for typography, forms, buttons, tables, grids, navigation, and etc.
