CSS Nesting syntax is not like Sass. And it was changed recently. If you have postcss-nesting, you need to change sources a little: Before: nested selectors must be started from & or @nest. Now: they must start from non-letter. You can wrap to :is(). github.com/ai/sitnik.ru/comm…

Hip and new meets old and gold: @remix_run framework released support for @PostCSS. It can process your existing CSS imports with PostCSS. This makes our Head of Frontend and the author of PostCSS, @sitnikcode, just a little bit happier! How about you? Have you tried Remix yet?
🥰 @remix_run now has support for PostCSS, and also provides a convenient "opt-in" layer to support @tailwindcss ❤️ github.com/remix-run/remix/r…

Replying to @stylelint
@stylelint 15.0.0 includes validation for property value syntaxes : stylelint.io/migration-guide… It is also extensible so you can still do a lot of custom stuff with PostCSS.
.tcss .tscss can someone start hackin on this please?! follow the ethos of typescript; stay close to CSS but enable enhancement syntax. CSS is a typed language. Its full of enums, functions and errors, but current tools barely give any of this feedback. nerdy.dev/tcss

The main difference of our official Browserslist website from alternatives is that we auto-update Can I Use database every day. browsersl.ist We added to the footer the date of latest update to explain this benefit to our users. And we polished the design a little.

There is a new #PostCSS plugin for vi and vb units in case you need to support older browser versions. (bundled with Preset Env) github.com/csstools/postcss-…
vi (inline) and vb (block) is like vh/vw, but use the writing mode of the current language (from left to right or from top to bottom like in Chinese)
