The view transition for these ones is going to be a PAIN but I already know it'll be so worth it 🤩

I knew it looked off, I added another container last minute and forgot to move the perspective property from the body haha, thanks, much better 🫶

Who's going to @weyweyweb.bsky.social?

Can't wait! I'm hosting a workshop on how to create cohesive animations with modern CSS 🎨 and giving a talk: "You might not need JS"✨

You can still register for the workshop, hope to see you there or at my talk the next day 🫶

This is not a new invention, of course, but I'm very happy with the new live coding slide I created for my reveal.js deck!

Just in time for my try-out workshop this Friday 🥳

Okay I might be going in a completely different direction now, how fun is this?!

🏗️ WIP

Created with CSS scroll driven animations, special shout out to color-mix too, that function has given me so much joy working with dynamic colors 🫶

Haha yes, I tried that too, but it looks like it just transitions like the --scroll-progress value is 1, and then snaps to the actual value it should be

🆘 I'm trying to do too a thing, that may or may not be possible with @property💅.

I'm using a scroll driven animation to update a css var that goes from 0-1, to translate items in the opposite way on hover. The calculation works, transition does not🥹

Here's a codepen:

I love view transitions, imagine having to do this with javascript ☠️

(still took me 4 hours to finetune, to be completely honest 😅)
