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.


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

Documentation search is powered by Algolia's DocSearch. Working on our search? Be sure to set debug: true in site/assets/js/search.js.

Running documentation locally

  1. Run npm install to install the Node.js dependencies, including Hugo (the site builder).
  2. Run npm run test (or a specific npm script) to rebuild distributed CSS and JavaScript files, as well as our docs assets.
  3. Run npm start to compile CSS and JavaScript files, generate our docs, and watch for changes.
  4. Open http://localhost:9001/ in your browser, and voilà.

Learn more about using Hugo by reading its documentation.

Documentation for previous releases

You can find all our previous releases docs on https://getbootstrap.com/docs/versions/.

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.
