Bootstrap 5 is hitting alpha and it’s jam-packed with changes. The biggest changes for me is a shiny new logo (very nice), a departure from using jQuery, and the dropping of support for Internet Explorer. You can read about more of the changes (including increased use of CSS custom variables) in this article.
Bootstrap 5’s very first alpha has arrived! We’ve been working hard for several months to refine the work we started in v4, and while we’re feeling great about our progress, there’s still even more to do.
Before you jump to updating, please remember v5 is now in alpha—breaking changes will continue to occur until our first beta. We haven’t finished adding or removing everything, so check for open issues and pull requests as you have questions or feedback.An excerpt from Bootstrap 5 alpha!
