It's common for folks who should know better — including people who work on browsers — to claim some vendors "don't follow standards" when attacking certain designs. This isn't just wrong, it hurts our ability to think clearly about how make a better web: infrequently.org/2025/09/stan...

comiCSS #210: Background-repeat oreos comicss.art/comics/210/ It was shared earlier this month, but just added it to the site. #css #cartoon #webdev

For those following along, Chrome is moving forward with shipping interest invokers, backed by a "Supportive" W3C TAG review. After 3+ years of prototype iteration, accessibility review, developer feedback, and standards discussions, it's clear that developers want this feature.

Did you see that we've released 2 new sessions on 2025.ffconf.org? That's TWO more reasons to attend!

COME TO BERLIN for @beyondtellerrand.com in November. We're planning some Big, Ambitious, Creative Things and I promise you're going to love it. beyondtellerrand.com/events/berli...

I wrote a short article about the :heading pseudo-class and function. alvaromontoro.com/tutorial/hea... It includes a little interactive section where you can play with the values and see how the affect the headings on the side. #css #webdev

I’m Not a Robot, a game about solving CAPTCHAs, is out now! good luck :) > neal.fun/not-a-robot/

in light of the current supply chain attacks, I've just published a @github.com action to detect packages that _lose_ their provenance. 📦 supports pnpm-lock.yaml, package-lock.json, yarn.lock (v1) 🎨 inline GitHub annotations ✅ JSON output + configurable 💪 published in TS with zero deps

CSS-only floating focus with anchor positioning We're using anchor positioning to duplicate our Track Focus debug tool (that shows a floating indicator around focused elements) using purely CSS. Follow the walk-through and check out the demo at the end! polypane.app/blog/css-onl...

Viewport behavior in Safari 26 is utterly broken. 🙄😭 Time to get Viewports into #Interop2026 because viewports on iOS have gotten only worse since I did the initial research in, *checks notes*, 2022 — github.com/web-platform...

Safari 26 is here!!! Anchor Positioning, Scroll-driven animations, High Dynamic Range images, the new HTML <model> element, the all-new Digital Credentials API, SVG icon support, WebGPU, WebKit in SwiftUI, every site can be a web app on iOS and iPadOS, and much more. webkit.org/blog/17333/w...

pnpm v10.16.0 adds "minimumReleaseAge", a setting for defining how long a version has to have been published before pnpm will install it. A nice countermeasure against accidental installs of short-lived compromised packages before they get taken down. Not a 100% fix, but a great additional step!

I've finally got around to documenting a cute way of building an Image Gallery with flexbox: bfgeek.com/flexbox-imag... This technique maintains image aspect-ratios, and ensures there is no additional free space (full-bleed). Let me know what you think! (@bram.us - I got around to this!)

👀 Browserslist 4.26 - Now supports Baseline Queries Thanks @en.sitnik.ru @tonypconway.com , this will be way more convenient in many cases!

🎤 Our speaker lineup so far: 🟣 Rune Devuyst on color, energy & accessibility 🟣 Brecht De Ruyte on Open UI primitives in browsers 🟣 Thorsten Jonas on Sustainable UX 🟣 Dylan Beattie on Rockstar, WebAssembly… and live guitar 🤘 Fronteers Dark Mode → fronteersconf.org

🎥 New (Video) Podcast: "Navigating the World of Web Accessibility with Sara Soueidan", with @kevinpowell.co www.youtube.com/watch?v=ndGK... I finally sat down with Kevin for a long-overdue, in-depth conversation about web #accessibility, and we had a blast!

🚀The new CSS sibling-index() and sibling-count() functions let us create staggered animations, dynamic color palettes, and even complex circular layouts with ease. I wrote about my first experiments with these fantastic new CSS additions. So much fun! ♥️ ✨ #CSS utilitybend.com/blog/styling...

You should come to @londonwebstandards.org #sotb2026 Early bird tickets are £70 And if you can’t afford it apply for a diversity ticket 2026.stateofthebrowser.com

In the latest Winging It, @miriam.codes & @stacykvernmo.com chat with #CSS expert @kizu.dev about how to create reusable and flexible CSS using mixins & functions, what happened in the CSSWG meetings, and what's coming in CSS! www.oddbird.net/2025/08/27/w... If you like the show, please subscribe!

I gave a talk on modern React patterns, including concurrent features, Actions, and the new <ViewTransition> component, at @reactuniverseconf.com last week. Watch the talk here! www.youtube.com/watch?v=I3As...

Definitely looking for someone to break down how to do some real nice stuff with view transitions on piccalil.li Stuff people can use in their day-to -day. Hit me up if that’s you!

If you thought we were done with View Transitions, guess again! A feature Chrome is working on, is “Scoped View Transitions”, which allow you to scope a VT to a subtree of the DOM. This unlocks things like concurrent transitions and prevents layering issues. developer.chrome.com/blog/scoped-...

Between the time we launched the original Learn CSS course on web.dev and today, container queries landed in browsers and became Baseline Widely available! It was high time for an update, and we were lucky enough to have the team at OddBird work with us. Enjoy 9 new modules! web.dev/blog/learn-c...

Was delighted to see this “popover on load” here on Bluesky! 🤩

This seems to be a little under the radar, but Chromium 140 ships with support for caret-shape! Instead of a regular bar, you can also have a block (like insert) or underscore (great for 2fa codes and other digits)

Seeing some nice proposals being made for #Interop2026: github.com/web-platform... If you want to suggest one (or more), now’s the time to do so.

Did you know your MacBook has a sensor that knows the exact angle of the screen hinge? It’s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door.

Chrome Dev Tools upgraded to straight up underlining problematic elements. I like it, points to Google ⭐️ Many people never open the Issues panel, this is much better integrated.

Rebased a 9 month old branch on a little project called Chromium. I think I can do an AMA on merge conflicts by now. 🫠 (Now off to the next challenge: will it compile? 😅)

That new Weval album … 🤤 album.link/be/i/1811689...

I missed this among all the great CSS updates: you can now use CSS to add syntax highlighting without overlaying extra elements on top of a textarea. Basic demo here from @bram.us. Browser support is solid. Very cool! www.bram.us/2024/02/18/c...

Interop 2026 has started asking for proposals. web.dev/blog/interop... What would you like to see being made more interoperable across all the major browsers?

You should come to Dordrecht (NL) on Friday October 3 for 🌒 Fronteers Dark Mode. fronteersconf.org The speakers are wonderful, and I heard the MC is quite OK too.

Journal: Speaking at Web Day Out Have you got the perfect talk for this event? Let me know! 🔗https://adactio.com/journal/22113

This incompatibility in Chrome – in which getComputedStyle would not include custom properties – has been on my radar for ages … and it’s about to get fixed! 🎉 (My frequent nagging to the Blink Style team about this is finally paying off 😅)

Hi @tent10.bsky.social 👋, The example here might make it clearer what it looks like to guard view transition name definitions with view transition types ;-) bsky.app/profile/vtba...

The super-early bird tickets for #SotB2026 end tomorrow! 2026.stateofthebrowser.com
