Animating zooming using CSS: transform order is important… sometimes
How to get the right transform animation.
jakearchibald.com
CSS uses a complex algorithm to decide how to animate transforms. If you get it wrong, as many folks do, you end up with an unnatural animation.
Here's how it works, and how to avoid the pitfalls.

@pfrazee.com hey, sorry to bother you. The folks at @publer.com are telling me there's a 50mb 'API limit' when uploading video.
That isn't my experience. But, can you set the record straight either way?

Ran into a bug with our JavaScript decorator setup, and wrote about it here frehner.me/blog/subclas...
Fun little bug when using decorators, metadata, and subclassing.

My mouse doesn't work properly because Logitech let one of their server certificates expire, so now their config software fails. What a time to be alive.

I just finished watching Players - a mockumentary about a League of Legends e-sports team, and it's one of the most unexpectedly-great things I've seen in ages.

I think this attitude will result in folks calling stuff AI that's actually just shitty human-written click-bait content and I'm absolutely fine with that.
if you're writing your post with AI, i'm not reading that shit to the end. not because i hate AI but because it's just not good enough. if i can spot it, it's skill issue both on your and AI part

I’m going to be the old man (41) who talks about understanding the code the AI generates and being able to write it by hand. The kids will say I’m out of date, and I’ll never be sure they’re wrong. The indignity will never be lost on me that I’m talking about hand-writing god damn Javascript.

@anatudor.bsky.social random-stuff.jakearchibald.com/house-of-cod... - in this example I've created a scaled shadow by creating a clone of the element & scaling it. Is there a way to do this without a clone?
I guess -moz-element() could, but is there a cross-browser way?

The video is about scroll-*triggered* animations which aren't even in in Chrome stable. Not scroll-*driven* animations, which work to a certain extent in every major browser, even if enabling a flag is required.
That aside, I'd expect Chrome devs to be able to use Canary...
