📣 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.

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

Interop 2025 graph shows Safari jumping from 64 to 98 in one fell swoop, this week. The blue line goes almost straight up, jumping ahead of all the other browsers. And the interop score line goes right with it.

Overall scores: Chrome 95, Edge 96, Firefox 90, Safari 98.

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)

📺 Video of my talk at CSS Day is up! It covers how to reduce climate impact at work (if you work in tech) you can watch it on Conffab, courtesy of @johnfallsopp.com conffab.com/presentation...

me on stage in front of slide that says 'there is only one grid'

slide that says “AGI” and that it is a) not well defined, b) not in existence, c) not sure if it can solve global warming

me in front of slide with screenshot of openai.com, search for global warming, which answered 'it looks like your question goes, emphasis starts, beyond what we can assist with there, emphasis ends.

slide that says 'what adds to the footprint of the www?' answers: A, Data centres;  Emissions of server hardware (making and running); B, Networks , Data downloads/uploads' C, Consumer devices: Manufacturing laptops, phones, tablets that access the web

Thank you Google AI overviews for being so useful <3

Google AI overview saying nonsense:

No, Xcode 26 cannot be used on macOS 15.5. Xcode 26 specifically requires macOS Sequoia 15.4 or later. macOS 15.5 is not supported.
Here's why:
* Xcode 26 requires macOS Sequoia 15.4 or later:
The official Xcode 26 release notes clearly state this requirement.
* macOS 15.5 is not supported by Xcode 26:
While Xcode 26 supports macOS Sequoia, it does not support all versions of it. Specifically, it requires 15.4 or later.
* Older Xcode versions may work on newer macOS:
It's possible to run older versions of Xcode (like 15.4) on macOS Sequoia 15.5, but this might not be ideal for development with the latest features and SDKs.
* Downloading older Xcode versions:
If you need to use an older Xcode version for compatibility reasons, you can download it from the Apple Developer Center.

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.

Styling HTML form controls is something web designers & developers have wanted for years! My team is working on a solution — apply `appearance: base` and switch to a new interoperable consistent default control. Then override it using new pseudo-elements.
