There's a defeatist vibe rn and I think there's an inevitability feeling washing over us. There is no inevitability. If you're in a position to speak up against the direction the industry is taking, I'd say now is the time to do that. I certainly try because I cannot be fired and it does help!

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!

You can follow bugzilla.mozilla.org/show_bug.cgi... to know when `@custom-media` will ship in @firefox.com At the moment, you can test them flipping `layout.css.custom-media.enabled` in about:config (Note that support in DevTools isn't fully done yet, see bugzilla.mozilla.org/show_bug.cgi...)

Digital Ocean ended their $50/month sponsorship of GNOME and FlatHub and went radio silent on CSS-Tricks right around the time they found a spare three million dollars to burn on “sponsoring” a high-profile racist’s dotfiles repo. Impossible to see this as anything but a statement of their values.

I added a class to the target so it can be styled (bugzilla.mozilla.org/show_bug.cgi...) even when the target isn't hovered hovered anymore (e.g. user moved the cursor inside the tooltip)

Yes definitely. In the Firefox Inspector, we have a tooltip to showing information about a given container query, and I wanted the actual query to be underlined so you can match the 2 things

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() ...

Nicolas Chevobbe @nicolaschevobbe.bsky.social · 28/07/2026

for the overridden declarations, that's all done on the client: searchfox.org/firefox-main... , which is not great. There's some work happening to do more things at the Stylo level, but that's a long quest

That's just a gut feeling, I didn't read the spec and I probably have some time until this gets added to Gecko :)

Ah yes, one place I wasn't thinking of: the button we have in computed panel to link to the declaration. if it's in a mixin, then you'd need to expand / show the mixin. Not the end of the world, but I think a lot of small things to think about

Nicolas Chevobbe @nicolaschevobbe.bsky.social · 28/07/2026

I think this part should be easy, yes. I think (at least in Firefox), it will pose some challenges for how we detect which declaration is actually being applied. Also, and I don't know if it's possible, showing the values for CSS variables defined in mixins might be interesting

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 🤩

A majestic view of mountains, on a beautiful day, with blue sky and a few clouds, from the top of "Le Grand Veymont", including a flat-top mountain called "Le Mont Aiguille"

oh, that's interesting custom functions are not implemented yet in Firefox but I was thinking we might need some good debugging tools for them, and a repl-like UI might be good. At least I can see how it could use part of what I'm working on at the moment (bugzilla.mozilla.org/show_bug.cgi...)

We have a warning for expensive `:has()` selectors at some point, but that's probably not going to scale super well. Making CSS perf issues easier to investigate in the profiler would be nice, but that's a niche tool IMO

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

Firefox DevTools Inspector with a tooltip displayed. The text of the tooltip says: Attribute value ("tree") does not match expected "<number>" syntax
