Bootstrap 4 Tutorial

Bootstrap 4 is a major rewrite of Bootstrap. After 2 years in alpha release, Bootstrap 4 has now gone beta!

This tutorial covers most of the functionality of Bootstrap 4. Most examples are interactive, so you can test things out as you go.

Bootstrap 4 alpha was released on 19 August 2015. After two years in various alpha releases, Bootstrap 4 finally made it to beta release in August 2017, then to beta 2 in October 2017. This release involves a major overhaul of Bootstrap with some big changes to the way it functions when compared to Bootstrap 3. There have been a lot of changes to most components, including tables, forms, grids, dropdowns, navbars, and more.

More info on the changes can be seen on the Bootstrap blog.

Release Plan

Bootstrap 4's development and release plan goes something like this:

Alpha Release (done)
The alpha release stage is now complete.
Beta Release (current)
Bootstrap 4 is now at the beta release stage, so its features and functionality won't change. You may still encounter some bugs. These should be fixed prior to the release candidate (RC) stage.
Release Candidate
Two release candidates are planned in order to test Bootstrap 4 rigorously in an environment closer to production.
Final Release
After the release candidates, comes the final release. This will be the official "Bootstrap 4.0.0" release (assuming Bootstrap still follows the Semantic Versioning guidelines.)
