View bobbing actually works quite well! 🤩
Not sure the animation is quite right yet though. I look like I have a limp :)

To celebrate something-or-other, I created a retro CRT using only vanilla CSS!

To celebrate the launch of Artemis II 🚀, I put together a #cssonly scroll-driven animation.

Powered by animation-timeline: scroll — no JavaScript, just modern CSS.

Still WIP, but already a fun experiment.

A new #cssonly carousel demo built around the :scroll-* pseudo-elements.

Using:
– CSS anchor positioning for centered placement
– container style queries to toggle between transition modes

A fun experiment with some modern CSS features.

@kevinpowell.co challenged me to adapt my rotation cube view-transition to a scroll-based animation. It kinda works with #CSSonly but I think using a bit of JS and view-transitions between sections would look better, I might try it in the future.

In supporting browsers (Chrome only currently), counters count up when scrolled into view.

Built with `timeline-trigger`, `animation-trigger`, `attr()`, `@property` and `sibling-index()`.

I've got the hobbledehoy movement working in the Backrooms, but I need to work on the interactions with it, because you can't currently press the light-switch. But it's fun to hobble around if you like:
