Use when optimizing GSAP animations, reducing jank, or when the user asks about animation performance, FPS, or smooth 60fps.\nlicense: MIT\n---\n\n# GSAP Performance\n\n## When to Use This Skill\n\nApply when optimizing GSAP animations for smooth 60fps, reducing layout\u002Fpaint cost, or when the user asks about performance, jank, or best practices for fast animations.\n\n**Related skills:** Build animations with **gsap-core** (transforms, autoAlpha) and **gsap-timeline**; for ScrollTrigger performance see **gsap-scrolltrigger**.\n\n## Prefer Transform and Opacity\n\nAnimating **transform** (`x`, `y`, `scaleX`, `scaleY`, `rotation`, `rotationX`, `rotationY`, `skewX`, `skewY`) and **opacity** keeps work on the compositor and avoids layout and most paint. Avoid animating layout-heavy properties when a transform can achieve the same effect.\n\n- ✅ Prefer: **x**, **y**, **scale**, **rotation**, **opacity**.\n- ❌ Avoid when possible: **width**, **height**, **top**, **left**, **margin**, **padding** (they trigger layout and can cause jank).\n\nGSAP’s **x** and **y** use transforms (translate) by default; use them instead of **left**\u002F**top** for movement.\n\n## will-change\n\nUse **will-change** in CSS on elements that will animate. It hints the browser to promote the layer.\n\n```css\nwill-change: transform;\n```\n\n## Batch Reads and Writes\n\nGSAP batches updates internally. When mixing GSAP with direct DOM reads\u002Fwrites or layout-dependent code, avoid interleaving reads and writes in a way that causes repeated layout thrashing. Prefer doing all reads first, then all writes (or let GSAP handle the writes in one go).\n\n## Many Elements (Stagger, Lists)\n\n- Use **stagger** instead of many separate tweens with manual delays when the animation is the same; it’s more efficient.\n- For long lists, consider **virtualization** or animating only visible items; avoid creating hundreds of simultaneous tweens if it causes jank.\n- Reuse timelines where possible; avoid creating new timelines every frame.\n\n## Frequently updated properties (e.g. mouse followers)\n\nPrefer **gsap.quickTo()** for properties that are updated often (e.g. mouse-follower x\u002Fy). It reuses a single tween instead of creating new tweens on each update. \n\n```javascript\nlet xTo = gsap.quickTo(\"#id\", \"x\", { duration: 0.4, ease: \"power3\" }),\n    yTo = gsap.quickTo(\"#id\", \"y\", { duration: 0.4, ease: \"power3\" });\n\ndocument.querySelector(\"#container\").addEventListener(\"mousemove\", (e) => {\n  xTo(e.pageX);\n  yTo(e.pageY);\n});\n```\n\n## ScrollTrigger and Performance\n\n- **pin: true** promotes the pinned element; pin only what’s needed.\n- **scrub** with a small value (e.g. `scrub: 1`) can reduce work during scroll; test on low-end devices.\n- Call **ScrollTrigger.refresh()** only when layout actually changes (e.g. after content load), not on every resize; debounce when possible.\n\n## Reduce Simultaneous Work\n\n- Pause or kill off-screen or inactive animations when they’re not visible (e.g. when the user navigates away).\n- Avoid animating huge numbers of properties on many elements at once; simplify or sequence if needed.\n\n## Best practices\n\n- ✅ Animate **transform** and **opacity**; use **will-change** in CSS only on elements that animate.\n- ✅ Use **stagger** instead of many separate tweens with manual delays when the animation is the same.\n- ✅ Use **gsap.quickTo()** for frequently updated properties (e.g. mouse followers).\n- ✅ Clean up or kill off-screen animations; call **ScrollTrigger.refresh()** when layout changes, debounced when possible.\n\n## Do Not\n\n- ❌ Animate **width**\u002F **height**\u002F **top**\u002F **left** for movement when **x**\u002F **y**\u002F **scale** can achieve the same look.\n- ❌ Set **will-change** or **force3D** on every element “just in case”; use for elements that are actually animating.\n- ❌ Create hundreds of overlapping tweens or ScrollTriggers without testing on low-end devices.\n- ❌ Ignore cleanup; stray tweens and ScrollTriggers keep running and can hurt performance and correctness.\n","# GSAP Performance\n\n## When to Use This Skill\n\nApply when optimizing GSAP animations for smooth 60fps, reducing layout\u002Fpaint cost, or when the user asks about performance, jank, or best practices for fast animations.\n\n**Related skills:** Build animations with **gsap-core** (transforms, autoAlpha) and **gsap-timeline**; for ScrollTrigger performance see **gsap-scrolltrigger**.\n\n## Prefer Transform and Opacity\n\nAnimating **transform** (`x`, `y`, `scaleX`, `scaleY`, `rotation`, `rotationX`, `rotationY`, `skewX`, `skewY`) and **opacity** keeps work on the compositor and avoids layout and most paint.
