Introducing Bootstrap.
Built on Bootstrap.
Built at Twitter by @mdo and @fat, Bootstrap utilizes LESS CSS. We enchanced it a little bit to fit into our projects.
Made for everyone.
Bootstrap was made to not only look and behave great in the latest desktop browsers (as well as IE7!), but in tablet and smartphone browsers via responsive CSS as well.
Packed with features.
A 12-column responsive grid, dozens of components, JavaScript plugins, typography, form controls, and more.
