Use the **position parameter** to place tweens at specific times or relative to other tweens.\n\n## Position Parameter\n\nThird argument (or position property in vars) controls placement:\n\n- **Absolute**: `1` — start at 1 second.\n- **Relative (default)**: `\"+=0.5\"` — 0.5s after end; `\"-=0.2\"` — 0.2s before end.\n- **Label**: `\"labelName\"` — at that label; `\"labelName+=0.3\"` — 0.3s after label.\n- **Placement**: `\"\u003C\"` — start when recently-added animation starts; `\">\"` — start when recently-added animation ends (default); `\"\u003C0.2\"` — 0.2s after recently-added animation start.\n\nExamples:\n\n```javascript\ntl.to(\".a\", { x: 100 }, 0);           \u002F\u002F at 0\ntl.to(\".b\", { y: 50 }, \"+=0.5\");      \u002F\u002F 0.5s after last end\ntl.to(\".c\", { opacity: 0 }, \"\u003C\");     \u002F\u002F same start as previous\ntl.to(\".d\", { scale: 2 }, \"\u003C0.2\");    \u002F\u002F 0.2s after previous start\n```\n\n## Timeline Defaults\n\nPass defaults into the timeline so all child tweens inherit:\n\n```javascript\nconst tl = gsap.timeline({ defaults: { duration: 0.5, ease: \"power2.out\" } });\ntl.to(\".a\", { x: 100 }).to(\".b\", { y: 50 }); \u002F\u002F both use 0.5s and power2.out\n```\n\n## Timeline Options (constructor)\n\n- **paused: true** — create paused; call `.play()` to start.\n- **repeat**, **yoyo** — same as tweens; apply to whole timeline.\n- **onComplete**, **onStart**, **onUpdate** — timeline-level callbacks.\n- **defaults** — vars merged into every child tween.\n\n## Labels\n\nAdd and use labels for readable, maintainable sequencing:\n\n```javascript\ntl.addLabel(\"intro\", 0);\ntl.to(\".a\", { x: 100 }, \"intro\");\ntl.addLabel(\"outro\", \"+=0.5\");\ntl.to(\".b\", { opacity: 0 }, \"outro\");\ntl.play(\"outro\");  \u002F\u002F start from \"outro\"\ntl.tweenFromTo(\"intro\", \"outro\"); \u002F\u002F pauses the timeline and returns a new Tween that animates the timeline's playhead from intro to outro with no ease.\n```\n\n## Nesting Timelines\n\nTimelines can contain other timelines.\n\n```javascript\nconst master = gsap.timeline();\nconst child = gsap.timeline();\nchild.to(\".a\", { x: 100 }).to(\".b\", { y: 50 });\nmaster.add(child, 0);\nmaster.to(\".c\", { opacity: 0 }, \"+=0.2\");\n```\n\n## Controlling Playback\n\n- **tl.play()** \u002F **tl.pause()**\n- **tl.reverse()** \u002F **tl.progress(1)** then **tl.reverse()**\n- **tl.restart()** — from start.\n- **tl.time(2)** — seek to 2 seconds.\n- **tl.progress(0.5)** — seek to 50%.\n- **tl.kill()** — kill timeline and (by default) its children.\n\n## Official GSAP Best practices\n\n- ✅ Prefer timelines for sequencing\n- ✅ Use the **position parameter** (third argument) to place tweens at specific times or relative to labels.\n- ✅ Add **labels** with `addLabel()` for readable, maintainable sequencing.\n- ✅ Pass **defaults** into the timeline constructor so child tweens inherit duration, ease, etc.\n- ✅ Put ScrollTrigger on the timeline (or top-level tween), not on tweens inside a timeline.\n\n## Do Not\n\n- ❌ Chain animations with **delay** when a **timeline** can sequence them; prefer `gsap.timeline()` and the position parameter for multi-step animation.\n- ❌ Forget to pass **defaults** (e.g. `defaults: { duration: 0.5, ease: \"power2.out\" }`) when many child tweens share the same duration or ease.\n- ❌ Forget that **duration** on the timeline constructor is not the same as tween duration; timeline “duration” is determined by its children.\n- ❌ Nest animations that contain a ScrollTrigger; ScrollTriggers should only be on top-level Tweens\u002FTimelines.\n","# GSAP Timeline\n\n## When to Use This Skill\n\nApply 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.\n\n**Related skills:** For single tweens and eases use **gsap-core**; for scroll-driven timelines use **gsap-scrolltrigger**; for React use **gsap-react**.\n\n## Creating a Timeline\n\n```javascript\nconst tl = gsap.timeline();\ntl.to(\".a\", { x: 100, duration: 1 })\n  .to(\".b\", { y: 50, duration: 0.5 })\n  .to(\".c\", { opacity: 0, duration: 0.3 });\n```\n\nBy default, tweens are **appended** one after another.
