CSS `random()`, now in Safari 26.2. Play around with it while waiting for other browsers to ship.

Do you have a favourite CSS one-liner?

Wondering what’s coming next in Safari 26.3? Well, check out the beta release notes: developer.apple.com/documentatio...

Which feature in Safari 26.2 is your favorite?? I always try to imagine the answer while writing… will they be more excited about command/commandfor or field-sizing? Are the HTML improvements the headline? Or CSS/SVG/JS…? Then I’m curious, what do you really think? webkit.org/blog/17640/w...

Safari 26.2 is here with 65 features + 165 bug fixes — including field-sizing, Navigation API, Largest Contentful Paint, command & commandfor, CHIPS opt-in partitioned cookies, scrollend event, random(), WebGPU in WebXR, scrollbar-color, hidden=until-found and much more! webkit.org/blog/17640/w...

Okay, on a serious note. Why do you struggle with CSS? #css

“The problem with Long COVID is that most of society would rather not see it.” @philipandrewhoover.bsky.social writes that he often feels that he’s living a double life. How can this sick side of him be so central, so enormous, yet so unseen by those who know and love him? bit.ly/4pf80g7

Beautiful @thesicktimes.org essay on how to be a friend to your friends who are affected by Long Covid—and why you should. Def worth a few minutes of your time.

I really can't wait to show you my CSS layout course. I'm learning a few things along the way. Currently, I'm working on some grid explanation and it's so much fun to have some aha-moments. Teaching is learning! ❤️ You can sign up for details: layoutmaestro.ishadeed.com

ok I've decided what my interop 2026 vote is (#interop2026)? `margin-trim` My fingers reach for it all the time only to be like, oh yeah, Safari-only. Imagine a `.card` with padding, it just *begs* for `margin-trim: block;`

The overall interoperability score for Interop 2025 has reached 92% test pass rate!! Looking good!

So happy that "Added WebGPU support for WebXR" (developer.apple.com/documentatio...) made it! Thank you!

Curious about web technology coming to Safari? How about field-sizing, position-visibility, random(), scrollbar-color, hidden=until-found, auto-expanding <details>, command & commandfor, Largest Contentful Paint, CHIPS, scrollend event, Navigation API & more! developer.apple.com/documentatio...

Safari 26.1 comes with many, many bug fixes! :)

Safari 26.1 arrives today. What does this bring developers? Many improvements to Anchor Positioning. A refactor of how WebKit handles CSS Units, bringing relative units (rlh, ic, cap, cqw, cqi, cqmin, cqmax) to SVG for the first time. And many other fixes. webkit.org/blog/17541/w...

There's a new #CSS Working Group poll to get feedback on different names for the infamous 'Pinterest' layout. - Since it uses many of the grid-* properties, `grid` will be in the name somewhere - We don't use metaphors in CSS names, so `masonry` is not listed here docs.google.com/forms/d/e/1F...

Between one thousand and four thousand tests fail in only one browser — out of over two millions tests. That’s still an incredibly high pass rate.

Got thoughts about Web Push? So many web developers talked about it for years… and now I hear nothing. Are you using Web Push? Have you learned about Declarative Web Push?

After seeing me with a horror novel my coworker told me that he wants to read something really scary so I sent him an article with the title: “Repeat COVID-19 Infections Could Double Your Risk of Long COVID.”

We’ve been busy over here. For those asking about “stable” — yes, the work that’s currently in Safari Technology Preview will land in stable. Yup.

Interop 2025 is looking good!

Largest Contentful Paint (from Core Web Vitals) is now available in Safari Technology Preview. webkit.org/blog/17504/r...

It’s really disheartening to see people who admit this regime is doing eugenics fail to understand the ways in which chronically ill, disabled, and immunocompromised people are just absolutely fucked by Long Covid

Meanwhile, there’s an incredible amount of offensive content on Sora — including video after video that’s deeply and shockingly anti-Semitic, and I haven’t heard anyone call it out.

I discovered a useful feature in Safari DevTools today. We can show the flex items order like (item #1, item #2, etc) and their corresponding order value (if it's changed). It's called "Order Numbers". @webkitgtk.org

i love the spreadsheet analogy here

Was surprised to see that, even though CSS Grid isn't a new feature, it's still high on the list of things devs find confusing, so wrote a post about it. I focus on a new mental model I think is helpful. Let me know what you think! webkit.org/blog/17474/c...

I wish Command Invokers had a different name that made it most easy for a web developers to understand what it is. I’d call it Button Commands.

I just learned web fonts have been supported for Initial Letter since Safari 18.4+. (Still prefixed, but before you couldn’t use a web font.) Yay!!! Have you used initial letter in CSS? Do you want to?

Anchor Positioning has a way to declare where the item appears. Use the `position-area` property with pre-named areas! @saron.bsky.social realized maybe some of the names are confusing. Read more & help decide — should the names be changed? webkit.org/blog/17417/p... What do you think??

Give folks their flowers No, I mean right now. Go tell someone you loved their work right now. They're on social media just say it, it has never been easier "They know how much people love--" no they don't go say it right now to a composer or artist or game dev or writer or anyone AAAAAAAHHHHHHHHH

I accidentally called someone on the phone phone, instead of FaceTime Audio. (Or Zoom/WebEx/etc.) Wow, the audio quality is of course much worse, and I am so much more tired afterwards. Phone audio quality is exhausting.

With everything going on, standing up for privacy is more important than ever. youtu.be/0HjDpPnxcP0

calling autism a “tragedy” and saying that there should be fewer autistic people are eugenicist talking points. Everyone who opposes such views also needs to recognize the ways in which everyday ableism left the door wide open for a person like RFK Jr.

Don't tell me boycotts don't work

Wow, people are really bending over backwards to justify shipping a new web API that definitely has a strong formal objection. So much twisting of logic to try and make it make sense. So many half-truths being stated as reality when they are not reality. The cognitive dissonance. The anger & hate.

Why am I suddenly seeing a bunch of well-known & well-respected web dev guys returning to X, using it as their main social media channel? Why am I not surprised? Disappointed. Jaded. Of course they are. Watching the mass public turn to the far right is hard.

Did you know that on macOS, you can update just to Safari 26, while remaining on macOS 15 Sequoia or even macOS 14 Sonoma? Go to  > System Settings > General > Software Update. Under “Also Available” you’ll find Safari listed. Click “Update Now”.

CSS `random()` just landed in Safari Technology Preview. We are the first browser to implement! “There are ongoing discussions in the CSS Working Group about the specification, and several open issues remain about whether this approach best serves developers.” webkit.org/blog/17285/r...

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...
