Use this skill whenever the user wants to build scroll animations, scroll effects, parallax, scroll-triggered reveals, pinned sections, horizontal scroll, text animations, or any motion tied to scroll position — in vanilla JS, React, or Next.js. Covers GSAP ScrollTrigger (pinning, scrubbing, snappin

GSAP & Framer Motion — Scroll Animations Skill Production grade scroll animations with GitHub Copilot prompts, ready to use code recipes, and deep API references. Design Companion: This skill provides the technical implementation for scroll driven motion. For the creative philosophy , design principles, and premium aesthetics that should guide how and when to animate, always cross reference the premium frontend ui skill. Together they form a complete approach: premium frontend ui decides the what and why ; this skill delivers the how . Quick Library Selector Need Use Vanilla JS, Webflow, Vue GSAP Pinning, horizontal scroll, complex timelines GSAP React / Next.js, declarative style Framer Motion whileInView entrance animations Framer Motion Both in same Next.js app See notes in references Read the relevant reference file for full recipes and Copilot prompts: GSAP → references/gsap.md — ScrollTrigger API, all recipes, React integration Framer Motion → references/framer.md — useScroll, useTransform, all recipes Setup (Always Do First) GSAP Framer Motion (Motion v12, 2025) Workflow 1. Interpret the user's intent to identify if GSAP or Framer Motion is the best fit. 2. Read the relevant reference document in references/ for detailed APIs and patterns. 3. Suggest the required package installation if not already present. 4. Implement the scaffold for the animation structure, adhering to the requested format (React components, hook requirements, or vanilla JS). 5. Apply the correct tools (scrolling vs in view elements) ensuring accessibility options are present and hooks don't cause infinite re renders. The 5 Most Common Scroll Patterns Quick reference — full recipes with Copilot prompts are in the reference files. 1. Fade in on enter (GSAP) 2. Fade in on enter (Framer Motion) 3. Scrub / scroll linked (GSAP) 4. Scroll linked (Framer Motion) 5. Pinned timeline (GSAP) Critical Rules (Apply Always) GSAP : always call gsap.registerPlugin(ScrollTrigger) before using it GSAP scrub : always use ease: 'none' — easing feels wrong when scrub is active GSAP React : use useGSAP from @gsap/react , never plain useEffect — it auto cleans ScrollTriggers GSAP debug : add markers: true during development; remove before production Framer : useTransform output must go into style prop of a motion. element, not a plain div Framer Next.js : always add 'use client' at top of any file using motion hooks Both : animate only transform and opacity — avoid width , height , box shadow Accessibility : always check prefers reduced motion — see each reference file for patterns Premium polish : follow the premium frontend ui skill principles for motion timing, easing curves, and restraint — animation should enhance, never overwhelm Copilot Prompting Tips Give Copilot the full selector, base image, and scroll range upfront — vague prompts produce vague code For GSAP, always specify: selector, start/end strings, whether you want scrub or toggleActions For Framer, always specify: which hook (useScroll vs whileInView), offset values, what to transform Paste the exact error message when asking /fix — Copilot fixes are dramatically better with real errors Use @workspace scope in Copilot Chat so it reads your existing component structure Reference Files File Contents references/gsap.md Full ScrollTrigger API reference, 10 recipes, React (useGSAP), Lenis, matchMedia, accessibility references/framer.md Full useScroll / useTransform API, 8 recipes, variants, Motion v12 notes, Next.js tips Related Skills Skill Relationship premium frontend ui Creative philosophy, design principles, and aesthetic guidelines — defines when and why to animate
