gsap-timeline
Official GSAP skill for timelines — gsap.timeline(), position parameter, nesting, playback. Use when sequencing animations, choreographing keyframes, or when the user asks about animation sequencing, timelines, or animation order (in GSAP or when recommending a library that supports timelines).
Why this skill is useful
Provides specific GSAP timeline commands and patterns for sequencing animations that the AI wouldn't reliably generate on its own.

What this skill does
GSAP Timeline Curated from GreenSock's official GSAP skills: https://github.com/greensock/gsap-skills When to Use This Skill Apply when building multi-step animations, coordinating several tweens in sequence or parallel, or when the user asks about timelines, sequencing, or keyframe-style animation in GSAP. Related skills: For single tweens and eases use gsap-core; for scroll-driven timelines use gsap-scrolltrigger; for React use gsap-react. Creating a Timeline By default, tweens are appended one after another. Use the position parameter to place tweens at specific times or relative to other tweens. Position Parameter Third argument (or position property in vars) controls placement: Absolute: 1 — start at 1 second. Relative (default): "+=0.5" — 0.5s after end; "-=0.2" — 0.2s before end. Label: "labelName" — at that label; "labelName+=0.3" — 0.3s after label. Placement: "<" — start when recently-added animation starts; ">" — start when recently-added animation ends (default); "<0.2" — 0.2s after recently-added animation start. Examples: Timeline Defaults Pass defaults into the timeline so all child tweens inherit: Timeline Options (constructor) paused: true — create paused; call .play() to start. repeat, yoyo — same as tweens; apply to whole timeline. onComplete, onStart, onUpdate — timeline-level callbacks. defaults — vars merged into every child tween. Labels Add and use labels for readable, maintainable sequencing: Nesting Timelines Timelines can contain other timelines. Controlling Playback tl.play() / tl.pause() tl.reverse() / tl.progress(1) then tl.reverse() tl.restart() — from start. tl.time(2) — seek to 2 seconds. tl.progress(0.5) — seek to 50%. tl.kill() — kill timeline and (by default) its children. Official GSAP Best practices ✅ Prefer timelines for sequencing ✅ Use the position parameter (third argument) to place tweens at specific times or relative to labels. ✅ Add labels with addLabel() for readable, maintainable sequencing. …
