Gsap Scrolltrigger

This handles scroll-driven animations with GSAP's ScrollTrigger plugin. You get pinning for sticky sections, scrubbing that ties animation progress directly to scroll position, snap points for locking to specific scroll positions, and parallax effects with multi-layer support. The skill covers the whole range from basic fade-ins on scroll to complex horizontal scrollers and batch animations for staggering groups of elements. It's solid for landing pages, storytelling sites, or anywhere you need animations that feel physically connected to scrolling rather than just triggered by it. The scrub parameter is the real workhorse here, with smoothing options that let you control how tightly animations follow the scroll.
