We provide compiled CSS and JS (<code>bootstrap.*</code>), as well as compiled and minified CSS and JS (<code>bootstrap.min.*</code>). CSS <a href="https://developers.google.com/chrome-developer-tools/docs/css-preprocessors">source maps</a> (<code>bootstrap.*.map</code>) are available for use with certain browsers' developer tools. Fonts from Glyphicons are included, as is the optional Bootstrap theme.</p>
