postcss-preset-env now includes the mixins and custom functions #postcss plugins: preset-env.cssdb.org/blog/postcss... Turns out that it is also possible to implement one of the gamut mapping algorithms as a custom function!

This is exciting. 😍 CSS Mixins and Functions are features that will transform how CSS is written and shared and this makes them usable, today! I'd use these via `@import url(…) supports(not at-rule(@function));` otherwise you get no benefit in browsers that support functions/mixins natively.

Web developers! Do you use html forms? Do you let forms submit or just use them for UI and call fetch()? Don’t use forms? Tell me why. Do? Tell me what’s painful. Let’s see if we can fix it!

Firefox 157 has landed, and includes a couple of useful CSS features: 🎉 at-rule() in @supports - lets you limit rules to browsers that support a given at-rule. 🎉 overscroll-behavior: chain - lets scrolling pass up to parent elements, but prevents UA effects like 'bounce' and overscroll. …And more!

Oh very nice! CSS Grid Lanes (aka Masonry) is enabled in Firefox Nightly (159) 😍 Wonder if this will "ride the trains" to the stable channel. Anyone know?

My computer screen, showing 2 Firefox windows, each one containing a different CSS Grid Lanes (aka Masonry) demo proving that the new layout system now works in Firefox. A third small window shows the About Firefox Nightly information, containing the version number 159.0a1.

I’ve been thinking about spacing #CSS units, considering using the em unit again. I have already been using lh/rlh unit spacing between content as of late.

At least in the circles I follow, there's been so much about educators leaving the space because of the various impacts of AI, but everyone is sick of the state of things. Push enough talent away, and bad things are going to happen. youtu.be/1aW7P3ZAUYw

@jensimmons.bsky.social I was wondering if there is any development regarding -webkit-font-smoothing? Is it still something that WebKit is looking to standardise or remove?

It's annoying to keep hearing about cool CSS features only to find out browser support isn't great, so today I take a look at a bunch of features that have fantastic support, but people still turn to JS for instead. youtu.be/qu1jE41O_8o

Another week, another package: show-keystrokes.netlify.app The native app I typically use to display keystrokes on the screen is disallowed by a corp policy. So I wrote a component to fill that gap. Embed it on your site and you’re good to go.
