What's included
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

└── fonts/

├── 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.
Bugs and feature requests
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.
Documentation
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.
Running documentation locally
1. If necessary, install Jekyll and other Ruby dependencies with
bundle install. Note for Windows users: Read this guide to get
Jekyll up and running without problems.
2. From the root /bootstrap directory, run bundle exec jekyll serve in
the command line.
3. 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
https://getbootstrap.com/2.3.2/ while folks transition to Bootstrap 3.
Previous releases and their documentation are also available for
download.
Contributing
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/.

Versioning
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.
Thanks
Thanks to BrowserStack for providing the infrastructure that allows us
to test in real browsers!
