Bootstrap is a sleek, intuitive, and powerful front-end framework for faster and easier web development, created by Mark Otto and Jacob Thornton, and maintained by the core team with the massive support and involvement of the community.
To get started, check out http://getbootstrap.com!
Several quick start options are available:
git clone https://github.com/twbs/bootstrap.git.
bower install bootstrap.
npm install bootstrap@3.
meteor add twbs:bootstrap.
composer require twbs/bootstrap.
Read the Getting started page for information on the framework contents, templates and examples, and more.
Within the download you’ll find the following directories and files, logically grouping common assets and providing both compiled and minified variations. You’ll see something like this:
bootstrap/ ├── css/ │ ├── bootstrap.css │ ├── bootstrap.css.map │ ├── bootstrap.min.css │ ├── bootstrap.min.css.map │ ├── bootstrap-theme.css │ ├── bootstrap-theme.css.map │ ├── bootstrap-theme.min.css │ └── bootstrap-theme.min.css.map ├── js/ │ ├── bootstrap.js │ └── bootstrap.min.js └── fonts/ ├── glyphicons-halflings-regular.eot ├── glyphicons-halflings-regular.svg ├── glyphicons-halflings-regular.ttf ├── glyphicons-halflings-regular.woff └── glyphicons-halflings-regular.woff2
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.
Have a bug or a feature request? Please first read the issue guidelines and search for existing and closed issues. If your problem or idea is not addressed yet, please open a new issue.
Note that feature requests must target Bootstrap v4, because Bootstrap v3 is now in maintenance mode and is closed off to new features. This is so that we can focus our efforts on Bootstrap v4.
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.
bundle install. Note for Windows users: Read this unofficial guide to get Jekyll up and running without problems.

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.
Please read through our contributing guidelines. Included are directions for opening issues, coding standards, and notes on development.
Bootstrap v3 is now closed off to new features. It has gone into maintenance mode so that we can focus our efforts on Bootstrap v4, the future of the framework. Pull requests which add new features (rather than fix bugs) should target Bootstrap v4 (the
v4-dev git branch) instead.
Editor preferences are available in the editor config for easy use in common text editors. Read more and download plugins at http://editorconfig.org.

For transparency into our release cycle and in striving to maintain backward compatibility, Bootstrap is maintained under the Semantic Versioning guidelines. Sometimes we screw up, but we’ll adhere to those rules whenever possible.
See the Releases section of our GitHub project for changelogs for each release version of Bootstrap. Release announcement posts on the official Bootstrap blog contain summaries of the most noteworthy changes made in each release.
