Good, there haven't been any new CSS creations lately, I hope you guys can keep updating for a while longer.

If you like simple drop in stylesheets this site has a whole bunch of cool options. https://dohliam.github.io/dropin-minimal-css/

Happy to see this, now that my beloved PicoCSS has been deprecated. Sumi looks really nice! https://picocss.com/docs/maintenance

I like the look of it! Small bug, opened an issue here: https://github.com/vladocar/Sumi.css/issues/1

I used a classless CSS framework once, for a project where I wanted a non-technical coworker to update an HTML file repeatedly throughout the week and then upload it to AWS/s3. I wanted it to be as simple for them as possible, to minimize errors, and it worked great. I'm not sure what other use cases are, but it's also just true that limitations can be fun.

Looks good! I created a similar alternative, Neat CSS, a while back. I use it for tons of projects. It could probably use a fresh look from me to see if there's anything I want to update but it's been a stable "framework" for me. I didn't intend it to be classless, though it's mostly semantic, but I instead focused on keeping it small and tight. It's only 3KB. Anyway, thought I'd share it here too. https://neat.joeldare.com

`<a href="#start" role="button">Get started</a>` Please, just use a link. This has a destination, so making it masquerade as a button gives so many false affordances.

Looks very nice, should add it to the list of classless CSS themes here. https://github.com/dbohdan/classless-css
