real question:

Does vibecoding just mean "used ai during coding" now?

I feel like it used to specifically mean agentic coding where you *only* use prompts/context and specifically don't write code yourself.

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;`

Google is shipping another VS Code fork with AI smashed into it (ala cursor, windsurf, trae, etc)

It's unclear to me if Microsoft is like "cool, the market position of VS code is super dominant" or "screw y'all making a billion dollars off the back of our thing doing exactly what we wanna do"

"Baseline doesn’t tell web developers if it is OK to use a feature that’s not Baseline yet, perhaps as a progressive enhancement, or by using a polyfill"

Yes, exactly. I'm glad they are thinking about this.

oh hi @firefoxnightly.bsky.social - Not a *bug* exactly but would love eyes on this if possible. blog.codepen.io/2025/11/18/4...

(short story: "un"supported `allow` attributes throw massive console noise, so UA sniffing required, and isn't great.)

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)

Ya'll got a way to block text messages (Apple ecosystem) with certain keywords? I get one from SmileDirectClub / SmileSet every day of my life and cannot find any way to stop them.

Remember how the bigger story with Responsive Design was how it affected company structure. The tech changes were, relatively, basic.

Anyway.

The Great (Refrigerator) Divide

I like a good hot sauce. It's not, like, my personality, but I enjoy them. There are enough different hot sauces that having a bit of a collection of them is reasonable. Cholula is a mainstay, working equally well on Mexican and egg-based dishes. Although admit…

I like a good hot sauce. It's not, like, my personality, but I enjoy them. There are enough different hot sauces that having a bit of a collection of them is reasonable. Cholula is a mainstay, working equally well on Mexican and egg-based dishes. Although admit Tabasco is my general go-to. The green Tabasco works particularly well on Chipotle for whatever reason.

I love that this actually works.

*Oh yeah, is your list actually UNordered? Prove it.*

browsers should shuffle the list items on every reload to enforce this.

What kind of list is unordered? I *know* you thought about the order — don’t even lie.

ol { list-style-type: disc; }

It’s okay. Embrace truth. Live mas.
