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
replyFor 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.
replyYes... there's a media query in the codepen disabling animation for people with reduced motion enabled.
replyIt's been behind a flag for ages. Maybe because of performance issues?
replyEnabling (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.

Noticed the same thing. In Mac Safari it works without setting any flags.
replytried 4 browsers, didn't work in any of them
replyFWIW it works on iPhone safari
replyBut it jumps around and flickers pretty bad. Chrome’s own demos in the docs don’t work at all.
replyhttps://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
Only on iOS 26.
replyI don’t think it did for me. Are you on iOS 26?
replyOnly worked for me on mobile (vivaldi android) not on vivaldi / chrome / edge on Desktop.
replyWhat an age where we need a pile of javascript as well as a bot check to demo a simple CSS trick.
replyThe JS and bot check are for making additional functionality, beyond just showing the example, work easily. I.e. editing and sharing edits from a browser. If all you want is a static example, feel free to make it without these things.
