📣 NEW! I’ve just released the BIGGEST and perhaps most creative project I’ve ever worked on! “Searching for Birds” searchingforbirds.visualcinnamon.com 🐤 A project, an article, an exploration that dives into the data that connects humans with birds, by looking at how we search for birds.

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

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

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

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...

I think `animation-composition: accumulate` is gonna see more action with `random()`, as it's like "take what you already got as a value and augment it rather than replace it". Here's a parallax thing where randomly-fixed-positioned stars are moved different amounts (with a scroll-driven animation)

Type-X is back! Easily test your fonts on *any* website with this Chrome extension. This was originally published about 5 years ago, but stopped working due to browser evolution. Now it's fixed, updated and ready to go! github.com/arrowtype/ty...

This has been in Safari since last year in version 18.2!

I love CSS folks. They are soldiers of joy and delight. The world is burning and AI debates have people at each others throats and CSS peeps keep being like “check out this dancing turtle I made out of divs 🥰”

The CSS Day 2025 photos are up at cssday.nl/2025/pix/pho... The interface is still a bit basic, but the photos are there for your downloading pleasure, especially if you had a team photo taken.

I love #CSSDay. It brings together so many of the CSS Working Group to share talks on the newest CSS features being worked on! If it wasn't for this conference, I never would have had the encouragement to join the working group last year. A huge privilege to be alongside these incredible people.

Safari 26 beta! webkit.org/blog/16993/n...
