There's an ideal set of sizing constraints for custom <select>, but the CSS is a bit tricky. Here's how to make it work, and a tour of new CSS features along the way. jakearchibald.com/2026/goldilo...

Firefox 159 has landed! This is a pretty big one for web dev stuff: 🎉 CSS scroll-driven animations, both scroll() and view(). 🎉 Scoped custom element registries. 🎉 Streaming sanitization of HTML. And more! developer.mozilla.org/en-US/docs/M...

I'm so gosh-darned excited! css-tricks.com/css-tricks-h...

JPEG XL is newly available in all major engines, but how does it stack up against other formats?

Apropos of nothing, if you're considering switching from a recently deprecated browser and want to try Firefox, I just landed `Copy Tab URL` in nightly - it's not bound by default but a quick visit to `about:keyboard` will let you set it, and also take a glance at the other neat shortcuts we have.

The claims here are really sus. Why compare to a 25+ yr old format rather than anything more modern like AVIF? Why claim HDR support, without making it clear that gain maps (an important part of HDR in varying environments) are not supported, yet they are in AVIF?

✍️ Just published a new post about my most-anticipated CSS proposals from Interop 2027! If you’re not familiar, the Interop project is a collaboration between browsers to pick shared focus areas. There’s *so much* good stuff this year, it was hard to pick just 10!

Did you know the State of HTML 2026 survey is currently open? Go take it and brush up on new (and old) browser APIs! survey.devographics.com/en-US/survey...

Can't believe that in less than 4 weeks I will be in Brighton to give a talk about how I build CSS DOOM at @ffconf.org Despite being on my bucket list to attend and speak for at least 10 years, I never managed to visit. But this year I will do both.✨ 🎟️ Tickets are still for sale: 2026.ffconf.org

The CSS Linked Parameters Module is cool. You can essentially pass parameters to SVGs that are embedded on the page using the image source or background image. @pepelsbey.dev has a great post about it! Vadim's post: pepelsbey.dev/articles/svg... Spec: drafts.csswg.org/css-link-par... #svg #css

JPEG XL has arrived on the web, but how does it stack up against AVIF? jakearchibald.com/2026/jpeg-xl...

If only it were that simple...

In Dublin on October 27, 2026? There's a web dev meetup organized by W3C. That's also the week when W3C organizes its big TPAC conference, so there will be a lot of browser and standards people at the meetup. A great opportunity to influence the web if you ask me.

Announcing our fourth speaker for Viewport 2027. Katie Fenn is a software engineer and co-organiser of Front End North, a front-end conference in Sheffield.

We've loved seeing folks post their rankings, so we've added a share button! You can either share your list via the site directly, or copy your list as markdown/html for your own blog. interop-rank.fxdx.dev

Going through the Interop list of features interop-rank.fxdx.dev and selecting and ranking the ones I want to see across browsers in 2027. I chose 15 features. At the top of my list are #HTML #a11y features `focusgroup`, ariaNotify(), `headingoffset` and `headingreset`.

I blogged about my picks for the Interop 2027 project: www.sarasoueidan.com/blog/interop... inspired by @vale.rocks @pawelgrzybek.com @tylersticka.com @ohhelloana.blog and others who have blogged about their rankings.

I'm really glad we're running this again. It helped us prioritise a lot of work this year. The previous method was 👍 on GitHub issues, which (imo) is too easily gamed, either intentionally or unintentionally.

FOMO over recent conferences? Or even from last year? Join us next month in Brighton for 2026.ffconf.org - join your peers, join the conversations you can't have with your chatbot, join us for 8 amazing talks and one superb day. Get your ticket today, don't FOMO-FFCONF.

My personal brain wants some things but my work brain wants others. So I was forced to blog about it: ohhelloana.blog/my-interop-2...

What do you want us to work on in 2027? Here's a web app where you can rank the Interop proposals you care about, giving us data we can use to prioritise feature development. interop-rank.fxdx.dev

And I wonder where you can see @cydstumpel.nl talk next 🤔 ::cough:: FFConf ::cough:: 🥳 (also heard great things about Dark Mode)

This was such a fun conference, and all the talks were brilliant. Events like this should have 10x the audience.

ah damn, RIP Margaret Hamilton. she took safety-critical software engineering seriously, and got people to the moon and back. news.mit.edu/2026/margare...

This and container tabs.

To celebrate the release of Preact 11, we’re hosting a design competition for the Preact website! We think it’s about time for a fresh look + marketing and would love to involve the community in the process. preactjs.com/blog/website...

Child reconciliation goes through Element.moveBefore() where supported. Reverse a list of 10 iframes: Preact 10 reloads 9, Preact 11 reloads 0, and the focused input stays focused.

Preact 11 is out 🎉 We’ve been hard at work at making our diffing use modern features like moveBefore , leveraging ESM for tree-shaking Preact Compat and ensuring you have a great experience with resumed hydration.

There are still tickets available for this

+++ The Venue +++ Everything happens in one place. Talks, coffee, dinner and conversations - no rushing between locations, just an evening focused on learning and meeting fellow frontend developers. See you at Fronteers Dark Mode? Fronteers Dark Mode Oct 2nd in Dordrecht 🇳🇱 🎟️ fronteersconf.org

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!

After careful consideration and a look at where the industry is spending it's funding we've decided to pivot #FFConf in a "new" direction. I present to you: ffconf.ai Please share with bots and humans alike.

Started working on my demo for Fronteers Dark Mode, this is built with CSS scroll-driven animations, no JS 💅 My talk will go into detail on where you can replace JS with CSS! Tickets are still available: fronteersconf.org This cool effect is inspired by @thomasaufresne.com → bennettandclive.com
