We provide compiled CSS and JS (bootstrap.*), as well as compiled and minified CSS and JS (bootstrap.min.*). CSS source maps (bootstrap.*.map) are available for use with certain browsers' developer tools. Fonts from Glyphicons are included, as is the optional Bootstrap theme.

Bugs and feature requests

Documentation

Bootstrap's documentation, included in this repo in the root directory, is built with Jekyll and publicly hosted on GitHub Pages at http://getbootstrap.com. The docs may also be run locally.

Running documentation locally

If necessary, install Jekyll (requires v2.5.x).

Windows users: Read this unofficial guide to get Jekyll up and running without problems.

Install the Ruby-based syntax highlighter, Rouge, with gem install rouge.
From the root /bootstrap directory, run jekyll serve in the command line.
Open http://localhost:9001 in your browser, and voilà.

Learn more about using Jekyll by reading its documentation.

Documentation for previous releases

Documentation for v2.3.2 has been made available for the time being at http://getbootstrap.com/2.3.2/ while folks transition to Bootstrap 3.

Previous releases and their documentation are also available for download.
