Download Bootstrap to get the compiled CSS and JavaScript, source code, or include it with your favorite package managers like npm, RubyGems, and more.

Compiled CSS and JS

Download ready-to-use compiled code for Bootstrap v4.1.1 to easily drop into your project, which includes:

  • Compiled and minified CSS bundles (see CSS files comparison)
  • Compiled and minified JavaScript plugins

This doesn’t include documentation, source files, or any optional JavaScript dependencies (jQuery and Popper.js).


Source files

Compile Bootstrap with your own asset pipeline by downloading our source Sass, JavaScript, and documentation files. This option requires some additional tooling:

  • Sass compiler (Libsass or Ruby Sass is supported) for compiling your CSS.
  • Autoprefixer for CSS vendor prefixing

Should you require build tools, they are included for developing Bootstrap and its docs, but they’re likely unsuitable for your own purposes.

Download source


Skip the download with BootstrapCDN to deliver cached version of Bootstrap’s compiled CSS and JS to your project.

If you’re using our compiled JavaScript, don’t forget to include CDN versions of jQuery and Popper.js before it.

Package managers

Pull in Bootstrap’s source files into nearly any project with some of the most popular package managers. No matter the package manager, Bootstrap will require a Sass compiler and Autoprefixer for a setup that matches our official compiled versions.


Install Bootstrap Material Design in your Node.js powered apps with the npm package:

npm install bootstrap-material-design@4.1.1

require('bootstrap-material-design') will load all of Bootstrap Material Design’s jQuery plugins onto the jQuery object. The bootstrap-material-design module itself does not export anything. You can manually load Bootstrap’s jQuery plugins individually by loading the /js/*.js files under the package’s top-level directory.

Bootstrap Material Design’s package.json contains some additional metadata under the following keys:

  • sass - path to Bootstrap Material Design’s main Sass source file
  • style - path to Bootstrap Material Design’s non-minified CSS that’s been precompiled using the default settings (no customization)
