Compiled CSS and JS

Download ready-to-use compiled code for Bootstrap v{{< param current_version >}} to easily drop into your project, which includes:

• Compiled and minified CSS bundles (see [CSS files comparison]({{< docsref "/getting-started/contents#css-files" >}}))
• Compiled and minified JavaScript plugins (see [JS files comparison]({{< docsref "/getting-started/contents#js-files" >}}))

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

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]({{< docsref "/getting-started/build-tools#tooling-setup" >}}), they are included for developing Bootstrap and its docs, but they're likely unsuitable for your own purposes.

Examples

If you want to download and examine our [examples]({{< docsref "/examples" >}}), you can grab the already built examples:

<a href="{{< param "download.dist_examples" >}}" class="btn btn-bd-primary" onclick="ga('send', 'event', 'Getting started', 'Download', 'Download Examples');">Download Examples

jsDelivr

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

<script src="{{< param "cdn.js_bundle" >}}" integrity="{{< param "cdn.js_bundle_hash" >}}" crossorigin="anonymous"></script>

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

<script src="{{< param "cdn.jquery" >}}" integrity="{{< param "cdn.jquery_hash" >}}" crossorigin="anonymous"></script>
<script src="{{< param "cdn.popper" >}}" integrity="{{< param "cdn.popper_hash" >}}" crossorigin="anonymous"></script>
<script src="{{< param "cdn.js" >}}" integrity="{{< param "cdn.js_hash" >}}" crossorigin="anonymous"></script>

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

require('bootstrap') will load all of Bootstrap's jQuery plugins onto the jQuery object. The bootstrap 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'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)

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', '~> {{< param current_ruby_version >}}'

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

gem install bootstrap -v {{< param current_ruby_version >}}

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:{{< param current_version >}}

NuGet

If you develop in .NET, you can also install and manage Bootstrap's CSS or Sass and JavaScript using NuGet:

Install-Package bootstrap

Install-Package bootstrap.sass
