There's me scrolling up and down and thinking "hey, it's not working!" But it's behind a flag on Firefox: https://caniuse.com/?search=view-timeline-name

For people saying it's not working in any browser - do you have some kind of reduced motion preference setting turned on? I can imagine that would have an effect on something like this and it's definitely working in Chrome for me.

		Yes... there's a media query in the codepen disabling animation for people with reduced motion enabled.

It's been behind a flag for ages. Maybe because of performance issues?

		Enabling (layout.css.scroll-driven-animations.enabled) and refreshing the codepen gives a "we crashed this to prevent a crash from an infinite loop" clicking to allow the infinite loops allowed me to see the animation. Fedora 44 Kernel: x86_64 Linux 7.0.10-201.fc44.x86_64 Firefox 151.0.2

Noticed the same thing. In Mac Safari it works without setting any flags.

		But it jumps around and flickers pretty bad. Chrome’s own demos in the docs don’t work at all. https://developer.chrome.com/docs/css-ui/scroll-driven-anima... Edit: Their reference works and has some really nice demos. Must be an iframe problem. https://scroll-driven-animations.style/#demos

		I don’t think it did for me. Are you on iOS 26?
