CSS Scroll-Driven Animation Generator

Scroll-driven animations are a modern CSS feature (animation-timeline: scroll()) that ties an animation's progress directly to scroll position — no JavaScript scroll listener required. This generator lets you pick an animation type and the scroll range it plays over, with a live preview, then copy the CSS.

How to use the CSS Scroll-Driven Animation Generator

Pick an animation type. Choose what animates as the user scrolls — fade, scale, slide and more.
Choose the scroll timeline. Select whether the animation tracks the whole page or a specific scroll container.
Set the entry/exit range. Control what portion of the scroll the animation plays over.
Copy the CSS. Copy the generated animation-timeline CSS for your scroll effect.

Frequently asked questions

What are CSS scroll-driven animations?

They're animations whose progress is driven by scroll position instead of time, using the animation-timeline property (e.g. animation-timeline: scroll()) — the animation plays forward and backward as the user scrolls.

Do I need JavaScript for scroll animations now?

No — animation-timeline lets you build scroll-linked effects (reveals, progress bars, parallax) in pure CSS, replacing a common use case for scroll-event JavaScript.

What browsers support animation-timeline?

Chrome and Edge support scroll-driven animations natively. Firefox and Safari support is still rolling out — test your fallback (a static or JS-driven animation) in those browsers.

What is the scroll entry/exit range?

It defines what portion of the element's scroll journey the animation actually plays over — e.g. only animating while the element is entering the viewport, not for its entire scroll distance.

Is this scroll animation generator free?

Yes — completely free with no sign-up, and it runs entirely in your browser.
