GitHubMotion & Animation · Scroll animation
Scroll interaction framework for pinning elements, scrubbing tweens and triggering callbacks against scroll position, with a visual debug indicator mode.
Why it’s a gem
Free ScrollTrigger predecessor; the built-in visual scene indicators are still unmatched.
Scroll animation library that mimics CSS keyframe syntax, letting you define percentage-based frames tied to scroll progress.
Vanilla scroll-animation plugin driving CSS transforms and filters from scroll position via a declarative preset syntax.
DevTools extension that lists scroll and view timelines on a page and visualizes their ranges and current progress.
Smooth-scroll runtime that virtualizes wheel input while keeping native scrollbars, anchors and accessibility behaviour intact.
Locomotive Scroll's API reimplemented on native scrolling plus Lenis, keeping the data-attribute syntax without the fake scroll container.
Library that reveals elements as they enter the viewport, with per-element distance, rotation, scale, interval and sequencing config.
