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 https://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

├── glyphicons-halflings-regular.svg

└── 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 https://getbootstrap.com/. The docs may also be run locally.

in your browser, and
voilà.Learn more about using Jekyll by reading its documentation.
Documentation for v2.3.2 has been made available for the time being at https://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.
Moreover, if your pull request contains JavaScript patches or features, you must include relevant unit tests. All HTML and CSS should conform to the Code Guide, maintained by Mark Otto.
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 https://editorconfig.org/.
