The left panel is titled AI - MASTER OF ENGINE & CREATION and features a sophisticated, human-like android robot with detailed internal circuits and a glowing brain. Floating text around the robot says - REWRITING GAME ENGINES with a small video screen, GENERATING REALISTIC VIDEO/IMAGES with code on a screen, and CONFIDENCE - 100%. The right panel is titled AI - FRONT-END CSS FAIL and shows a cluttered desk with a distressed small robot next to a frustrated human man pointing aggressively at a computer screen. The computer displays a chaotic webpage full of broken layout elements and a giant black void called a gaping hole. The small robot has a speech bubble that says - I'M DONE! THE FEATURE IS COMPLETE. Floating text phrases on the right side are - BESPOKE INTERACTION NIGHTMARE, CSS IS HARD, YOU'RE ABSOLUTELY RIGHT, CAN'T RENDER, LLM CAN'T MATH. The human has a mug with </> and nerdy.dev written on it.

Why does AI suck at front-end?

🗑️ trained on garbage
👀 it can't see
❓ it doesn't know why
🏞️ no environmental control

there's no human v20.2.1 to target. we're a LLM combinatorial explosion

What's My JND? Find your Just Noticeable Difference in colour perception. How small a colour difference can you actually see?

I guess 0.0051 is okish for a late night attempt. Great app 👍

Not a real app if there’s no VDOM

Two graphs, the first one being "Preact.js downloads over time" 2015-2025, the other being "UFO sightings over time" 1940-2015, showing a vaguely similar increasing trend over time.

A GitHub-style pull request merge confirmation. It adds a tipping interface with options (15%, 20%, 25%) and a "Custom Tip" button, plus a "No thanks, just merge" option, turning the merge action into a tip jar moment.

oh what the hell

I hope you don’t suggest: ditch web components for react

Something, something, AI

Another API proposal from TPAC: CSS routes and navigation queries, meaning less JavaScript is needed for view transitions!

How broken is today's frontend culture?

A friend points out that the median *mobile* page is now larger than a copy of DOOM (2.6 MiB vs. 2.48 MiB), the 75th percentile page is more than 2 DOOMs, and the P90 mobile page is 4.5x the size of DOOM:

Chrome DevTools showing that Temporal.Now does work, and that other properties are also available.

Temporal you ask? In all browsers you ask?

Well, I'm told it's coming to Chrome/Edge 144. So, like, very very soon (as in, January).

It's already in Firefox. And being implemented in Safari too.

Ermh, could we have a sneak peak of that code?

Does it work also for `size: stretch;`?

What should a native DOM templating API look like?

Ok, here's my second post on a potential native DOM templating API, diving into exactly what such an API should actually look like and why.

JavaScript broke the web (and called it progress) We replaced simple websites with complex apps nobody asked for. Now it takes a complex build pipeline just to change a headline.

Okay gang, those who sling HTML, CSS, JS, which _Firefox_ bugs are blocking you? Which features do you think need improving? What new features would you like to see? What work would you prioritise? Big or small, bonus points for linking to a bug (even more for filing bugs then linking them)!

Yay
