Gecko: Intent to Prototype: CSS at-rule() function for @supports

Firefox 154 arrives pretty soon and I genuinely can't contain my excitement 😇 text-box-trim was the first "big" feature I wanted to contribute but it felt like it was a bit beyond my reach. So I started on some other layout work, and took a detour to work on sibling-index() and sibling-count() ...

Firefox now supports the text-box-trim and text-box-edge CSS properties, and the associated text-box shorthand. These properties allow you to control the leading space above and below text, enabling simpler and consistent vertical spacing and alignment. bugzilla.mozilla.org/show_bug.cgi...

This weekend I hiked 20km and 1000m in elevation to get to the top of "Le Grand Veymont" in the Vercors mountains (in France, about 1h from where I live) The climb was pretty rough, but the view was very rewarding 🤩

CEO Reveals How He Used AI To Build One-Person Company That's $1.3 Billion In Debt

Right now the world is full of people who want to code and write and paint and film stuff and people who want to play and read and look at and watch stuff and nobody is allowed to do any of that because some unrelated third guy isn't making enough money off the deal

Our games industry is people. Our studios are people. Our teams people, our games by people for people. Our games are made by people, in groups of people, in teams of people, making people things for people. The magic is people, and the people deserve so much better than all this. I am so sorry.

Allez, j'ai une anecdote au sujet de Monique Barbut. Il y a quelques mois, préoccupée que son invisibilité ne nuise à son plan de carrière, elle a décidé de lancer un truc médiatique qui lui permette de rassembler les caméras. Et elle a pensé au lynx.

It's so nice seeing the excitement around this! I've had a lot of fun building this, took a little longer than I expected but I learned a ton. Looking forward to launching for everyone in Firefox 154. 😀

`sibling-index()` and `sibling-count()` are currently being prototyped in Firefox¹, hopefully available soon for testing :) #cssday ¹ groups.google.com/a/mozilla.or...

Here you go! (Except I've been told that the guy in the middle is, in fact, not Jake. Maybe a little bit of AI magic can fix that? 😅)

Watching @meyerweb.com talk, I guess we should have some Firefox DevTools for `ray()` There's bugzilla.mozilla.org/show_bug.cgi... for this, tell us it's important for you (or any blocking bug of bugzilla.mozilla.org/show_bug.cgi... that covers the functions you can use in offset-path) #cssday

You heard it here first — 2026 is the year you can finally style a select!! It will be in all browsers by the end of the year 🎉🎉🎉 @jakearchibald.com #cssday

Modern attr() is behind `layout.css.attr.enabled` in Firefox (set it in about:config). It's enabled by default in @firefoxnightly.bsky.social In Firefox DevTools, there will be a tooltip when the attribute value doesn't match the type you declare in CSS #cssday

Hey @bram.us 👋 While doing some testing, I found this issue in the Chrome Inspector: the color swatch in the color declaration should be lime(-ish), not red

recently saw this TERRIBLE advice to “write more human”: - don't use “curly” quotes, use straight quotes ( " and ' ) - don't use en or em-dashes, use -- and --- - never use an ellipsis (…), use three dots (...) please for the love of god don't write worse because ai exists. good typography is cool!

a weird side effect of enjoying writing and reading is that I’ve been accused a few times of using LLMs to write because I do things “humans don’t do” (e.g. use a semicolon properly)

CSS's light-dark() now accepts images, making it simpler to define alternate values for a dark color scheme. Here's how it works:

I may as well reshare it myself 😇

sizes="auto" landed in Firefox 150, making responsive images simpler and more reliable. Here's when you can use it, and how…
