Bootstrap 4 with two additional breakpoints:

• xxl - min-width: 1900px (desktops at full screen)
• xxxl - min-width: 3000px (4k at full or near full screen)

Use these as you would other breakpoints, e.g. <div class='col-12 col-md-6 col-lg-4 col-xl-3 col-xxl-2'>. The container max-width is increased for these breakpoints as well. See it in action at thunderblaster.github.io/bootstrap-xxl.

To use, simply download and link dist/css/bootstrap.min.css and dist/js/bootstrap.min.js, or the non-minified or bundled version if you prefer.

Now available from npm!

npm install bootstrap-xxl
