Compiled CSS and JS
Download ready-to-use compiled code for Bootstrap v4.3.1 to easily drop into your project, which includes:
- Compiled and minified CSS bundles (see CSS files comparison)
- 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.
Skip the download with BootstrapCDN to deliver cached version of Bootstrap’s compiled CSS and JS to your project.
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 in your Node.js powered apps with the npm package:
const bootstrap = require('bootstrap') or
import bootstrap from 'bootstrap' will load all of Bootstrap’s plugins onto a
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.
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)
Install Bootstrap in your Node.js powered apps with the yarn package:
Alternatively, if you’re not using Bundler, you can install the gem by running this command:
See the gem’s README for further details.
