gsap-scrolltrigger — Skills

What it does

triggers: selector text (e.g. ".box") or Array of elements.

scroller: selector or element (e.g. "body", ".container").

scrollWidth / scrollHeight — Getter/setter functions (same pattern: argument = setter, no argument = getter) when the library exposes different dimensions.

When removing animated elements or changing pages (e.g. in SPAs), kill associated ScrollTrigger instances so they don’t run on stale elements:

✅ gsap.registerPlugin(ScrollTrigger) once before any ScrollTrigger usage.

✅ Use scrub for scroll-linked progress or toggleActions for discrete play/reverse; do not use both on the same trigger.

✅ For fake horizontal scroll with containerAnimation, use ease: "none" on the horizontal tween/timeline so scroll and horizontal position stay in sync.

Scroll-linked animations, pinning, scrubbing, and trigger-based callbacks for GSAP timelines and tweens.
