Bootstrap 5 Beta 3

@mdo March 23, 2021

Our final beta for Bootstrap 5 has come with some amazing new changes (including a new component!), documentation updates, and more. We’ve also fixed some important bugs since our last release, in particular with our dependencies. Next up is our stable release!

Keep reading for a recap of what’s new in Beta 3.

New offcanvas component

Offcanvas example

Thanks to our newest team member, @GeoSot, we have a brand new component to unveil in Beta 3—introducing offcanvas! Built on and sharing fundamental pieces of our modals, the offcanvas comes with configurable backdrop, body scroll, and placement. Offcanvas components can be placed on the left, right, and bottom of the viewport. Configure these options with data attributes or via the JavaScript APIs.

We’re excited about iterating on the new offcanvas component and building additional examples and demos with you. Please share any feedback on an issue or pull request as you start to use it in your projects.

New and refreshed examples

New examples

Our examples have been updated in Beta 3 as well. We’ve added four brand new snippet-heavy examples and refreshed a few others. New with this release are several snippets for headers, heroes, features, and sidebars. These new snippets will continue to grow with new additions over time, showing just how fun and easy it is to build with Bootstrap.

New starter example

We’ve also updated our starter template with a refreshed, simplified design and more resource links. We’ll also incorporate this new look and feel into our npm starter project project, and eventually add a Parcel starter project.

Lastly, we’ve updated our pricing, checkout, and sign-in examples. We’ve also added a new jumbotron example to show you how to create your own jumbotron since we removed it in Bootstrap 5.

Improved Sass docs

New Sass docs

Since our last release, we’ve added a new section to nearly every component and utility documentation page for the source Sass code. Where appropriate, we now list Sass variables, maps, loops, and animation keyframes. These are directly linked from our source files, so whenever we ship new code, they’ll automatically be up-to-date.

And more!

Some highlights from the rest of our documentation updates and bugfixes include:

  • Added new .list-group-numbered variation to list groups that uses pseudo-elements for numbering list group items.
  • Removed explicit focus state suppression in Reboot
  • Improved carousel swipe behaviors for RTL
  • Updated accordions to improve transitions and borders when animating
  • Updated Sass customization docs to show how to properly override default variables
  • Fixed tooltips not appearing after rapid focus in and out
  • Fixed dropdown events not bubbling and forms inside dropdowns not propagating
  • Removed flip option from dropdowns
  • Disabled select now render consistently in Chrome
  • Button elements now grow in .nav-fill and .nav-justified
  • JavaScript plugin constructors now accept CSS selectors
  • De-duped the .border-0 utility
  • Fixed event handler removal in dropdown/carousel dispose
  • Added new Parcel guide to the docs
  • Added input focus blur Sass variable
  • Updated .browserslistrc to drop Android and add Safari/iOS 12 as the new minimum version (completing our two latest major releases guideline for supported browsers).
