Download

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 v5.1.3 to easily drop into your project, which includes:

This doesn’t include documentation, source files, or any optional JavaScript dependencies like Popper.

Download

Source files

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

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

CDN via jsDelivr

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

If you’re using our compiled JavaScript and prefer to include Popper separately, add Popper before our JS, via a CDN preferably.

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.

npm

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

npm install bootstrap

const bootstrap = require('bootstrap') or import bootstrap from 'bootstrap' will load all of Bootstrap’s plugins onto a bootstrap object. The bootstrap module itself exports all of our plugins. You can manually load Bootstrap’s plugins individually by loading the /js/dist/*.js files under the package’s top-level directory.

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

  • sass - path to Bootstrap’s main Sass source file
  • style - path to Bootstrap’s non-minified CSS that’s been precompiled using the default settings (no customization)
Get started with Bootstrap via npm with our starter project! Head to the twbs/bootstrap-npm-starter template repository to see how to build and customize Bootstrap in your own npm project. Includes Sass compiler, Autoprefixer, Stylelint, PurgeCSS, and Bootstrap Icons.

yarn

Install Bootstrap in your Node.js powered apps with the yarn package:

yarn add bootstrap

RubyGems

Install Bootstrap in your Ruby apps using Bundler (recommended) and RubyGems by adding the following line to your Gemfile:

gem 'bootstrap', '~> 5.1.3'

Alternatively, if you’re not using Bundler, you can install the gem by running this command:

gem install bootstrap -v 5.1.3

See the gem’s README for further details.

Composer

You can also install and manage Bootstrap’s Sass and JavaScript using Composer:

composer require twbs/bootstrap:5.1.3

NuGet

If you develop in .NET Framework, you can also install and manage Bootstrap’s CSS or Sass and JavaScript using NuGet. Newer projects should use libman or another method as NuGet is designed for compiled code, not frontend assets.

Install-Package bootstrap
Install-Package bootstrap.sass
