Bootstrap is Twitter's toolkit for kickstarting CSS for websites, apps, and more. It includes base CSS styles for typography, forms, buttons, tables, grids, navigation, alerts, and more.

To get started -- checkout http://twitter.github.com/bootstrap!


You can use Twitter Bootstrap in one of two ways: just drop the compiled CSS into any new project and start cranking, or run LESS on your site and compile on the fly like a boss.

Here's what the LESS version looks like:

<link rel="stylesheet/less" type="text/css" href="lib/bootstrap.less">
<script src="less.js" type="text/javascript"></script>

Or if you prefer, the standard css way:

<link rel="stylesheet" type="text/css" href="bootstrap-1.0.0.css">

For more info, refer to the docs!

We have included a makefile with convenience methods for working with the bootstrap library.

  • build - make build This will run the less compiler on the bootstrap lib and generate a bootstrap.css and bootstrap.min.css file. The lessc compiler is required for this command to run.

  • watch - make watch This is a convenience method for watching your less files and automatically building them whenever you save. Watchr is required for this command to run.
