Bootstrap turned 15! To celebrate, I'm happy to share that the first v6 alpha is coming soon! Buttoning up a few things and writing a lengthy blog post to highlight the new Sass+CSS approach, new components & plugins, new standards, new theming, and more. Stay tuned.

The nostalgia seeing this homepage is crazy I remember copy pasta’ing the ever living crap outta those three basic templates at the bottom of the page In many ways, bootstrap kicked off the modern SV dev scene as we know it. Design system w/ variables, components, etc. It took the ecosystem the following 9 years of the decade to fully flesh these core ideas out with things like React, storybook, etc @fat @mdo are goated. Also, honored to have stackblitz powering the live examples on the bootstrap site the past years!

Lots of happenings lately for v6's development! One new idea is to move from component-specific modifiers to global ones. Take this example—use `.theme-primary` on all components, or on a parent, and even override where needed. Also, spot the new button variants? 👀

These theme modifiers are generated from the new theme colors map we've been building. Looks a little wild, but the use of CSS's `light-dark()` color function makes these also immediately adaptive to OS color modes.

Oh, and we have new colors! First, there are more named colors in here—like violet, amber, lime, brown, and pewter. And there are more tints and shades—025, 050, 950, and 975 values are here for every color.

Would you prefer a v5 breaking change to support Sass modules (drop Node Sass, modify imports, iron out a few customizing issues)? Or a jump right to v6?

Just a heads up—we have two big efforts underway for Bootstrap with migrating the docs to Astro for our next v5.3 release and early v6 development. Astro unblocks us from dropping Node Sass, which will allow us to focus on Dart Sass and those deprecation warnings. Coming soon!

It's early to be thinking about v6 more holistically, but it's still fun to capture easy changes we really can't make until then on @pierrecomputer for now. For example, a breaking change like moving ratio helpers to utilities. pierre.co/share/c61e6401-9f8…

Friends writing CSS/Sass... are you using imports or the module system (use, forward)?

We've had lots of requests for a stepper component in Bootstrap, so the other day I whipped one up as a draft on @pierrecomputer. Starts stacked vertically on mobile and then has modifier classes to go horizontal. Either coming in a v5.4 or a v6 release. pierre.co/share/3fb20635-008…
