@kevinpowell.co I’m listening to your podcast episode about Interop 2026. Congrats on getting it out so soon! I hear you wondering about “Dialogs & Popovers” support in Safari. It’s wrong to think that means our implementation of dialog and popover is poor. Nope! The focus area name is confusing 🤪

Grid: for creating containers for fluid content to fill Flexbox: for stacking rigid blocks of content in the most efficient way possible Does this even make sense? Intuitively, grid is rigid and flexbox is fluid. But it's the other way around for their contents? ??? #vagueCSS

Interop 2026 launches today! If you want know on what it includes and what it means for web development — our article provides all the details. webkit.org/blog/17818/a... Focus areas include Anchor Positioning, Style Queries, contrast-color(), WebTransport and much, much more.

I’m seeing so much about LLMs in my feed today. Web designers and developers — how are you feeling about AI and what it means for your work? Are you using the tools? How? What’s changing? How do you expect AI to be used in the future for making websites & web apps?

Safari 26.3 is here with Zstandard file compression, Navigation API’s AbortSignal for better control in single-page apps, and fixes for anchor positioning, multi-column layouts, & more. Plus fullscreen video now dims surroundings in visionOS. webkit.org/blog/17798/webkit-features-for-safari-26-3/

CSS grid lanes are arriving sooner than you think. @jensimmons.bsky.social says Safari Technology Preview has the finalized syntax, while Chrome and Firefox are close behind. Meanwhile, you can use @​supports for progressive enhancement and a CSS or JS polyfill fallback. webkit.org/blog/17758/w...

Are you using CSS Grid? If you write CSS & code layouts on the web, and not using Grid — why not?!? I see so many sites that still use only Flexbox for 100% of their layout. 0% Grid. Why? What would help? I hear people say it’s hard. Is it? What’s hard? What do you want to learn about CSS Grid?

When will CSS Grid Lanes arrive? How long until we can use it? from @jensimmons.bsky.social on the webkit blog webkit.org/blog/17758/w...

It’s wild to me just how much wrong information there is out there (written by humans in the later half of 2025) about using CSS to create masonry layouts. There is no property named `grid-lanes` (as in grid-lanes: repeat(4, 200px)). There is no `masonry-direction` property. Or `masonry` anything.

Whoop! Updating my CodePen! codepen.io/dutchcelt/fu...

I’ve been using r/lh unit for typography related content. A perfect example of this is @jensimmons.bsky.social article on vertical rhythm.

Excited about CSS Grid Lanes? Wondering when you can start using it? We’ve got you covered. Updates on browser implementations + strategies for progressive enhancement. webkit.org/blog/17758/w...

Web designers/developers, What are your biggest questions about CSS Grid Lanes?

Are you excited about CSS Grid Lanes? It can be tricky to fully understand how content order works in this layout. Safari Technology Preview 235 just landed a new Order Number tool in our Grid Inspector to quickly see what’s up. Especially helpful with `flow-tolerance`. webkit.org/blog/17746/n...

📝 Algorithmic hover states with contrast-color() - Taking some cool new features for a spin. daverupert.com/2026/01/algo...

Today the CSS Working Group resolved to rename the property that lets you adjust the tolerance of how content lays out in CSS Grid Lanes to `flow-tolerance`! Just updated the article about it with the new name. webkit.org/blog/17660/i...

Any Focus Area that still needs work is considered for Interop 2026, but it’s not included automatically. Maybe some of these will be carried over? (Not individual failing tests, but whole areas.) Depends. It also might be more important to move on to other features to improve them.

Happy new year! Ah, now we can checkout the results of Interop 2025 — and see the entire year on the dashboard. wpt.fyi/interop-2025... Safari might have started the year in last place, but we definitely ended in first. (Interop Project tracks automated test pass rates for specific web API.)

FINAAAAALLLYYYYYYY

I enjoyed catching up on this post while I was on vacation.

Have you been wishing masonry layouts would just hurry up and arrive in CSS?? Well, happy holidays! webkit.org/blog/17660/i...

Congrats to the Safari team. It's been years since Safari is the new IE meme was accurate.

Check out all the revised demos of Grid Lanes in Safari Technology Preview 234! webkit.org/demos/grid3/

More holiday cheer. For those of you asking about Safari’s “stable” Interop 2025 score…

The WebKit team is pushing out new features at lightning speed right now!

Did you see everything in Safari Technology Preview 234? webkit.org/blog/17674/r... It’s got a lot of new features including Grid Lanes, Threaded Scroll-driven Animations, seven new Web API, and more. Plus a TON of other improvements & fixes.

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!
