Today in the studio, I’m recording a short CSS tip and writing about JointJS MCP. Tomorrow, I’ll be at @weblicahr, learning, connecting, and talking with fellow developers.

If you see me there, come say hi, especially if you want to chat about CSS, JavaScript, @jointjs , diagramming, AI workflows, or anything in between. 👋

Just launched YouTube Channel Visualizer, a free browser-based app to explore and analyze any YouTube channel on an interactive canvas.

Posting a 25s teaser here. I’ll drop the tool link and full 12-min walkthrough in the first reply.

My last YouTube video — a humorous take on Claude Code Leak — was watched over 10k times in the first week after I published it. 🙏

So I'm thinking I should maybe do more funny takes on breaking news in the CSS/AI/coding space. 🤪

Did you hear that Claude Code's source code was leaked via their NPM registry? 😱

Well, I tried to have some fun with it. 😎

@LumaLabsAI Just as with my previous tweet, I tried using the same prompt in GPT Image 1.5—the resulting image shows completely wrong code. 🙈

[CSS Weekly @CSSWeekly]

Safari 26.4 is the first browser to support CSS Grid Lanes—no more JS libraries or weird hacks to build masonry layouts. 🚀

Have you played with it already?

PS. I generated the preview image with @LumaLabsAI Uni-1. 🔥

@FrancescoCiull4 👋

[CSS Weekly @CSSWeekly]

I also tried generating the preview image in GPT Image 1.5 using the same prompt.

It’s so silly, I just had to share the result here—from image style to listing features from the wrong Safari version (26.0 instead of 26.4) 😜

[CSS Weekly @CSSWeekly]

New WebKit Features in Safari 26.4
🧱 Grid Lanes
📦 Name-Only Container Queries
🧮 Math Typography
🔎 Zoom (fixes)

PS. I generated the preview image with @LumaLabsAI Uni-1. 🔥

[CSS Weekly @CSSWeekly]

I've been playing with a lot of image generation tools lately, and my initial impressions of Luma's Uni-1 are very positive. 🙂

I'll share some CSS-themed results later. 😉

[Luma @LumaLabsAI]

Uni-1 is here! A new kind of model that thinks and generates pixels simultaneously. Less artificial. More intelligent.
