Download

    Download ready-to-use compiled code for Bootstrap v4.5.0 to easily drop into your project, which includes:

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

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