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).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GSAP Timeline
## 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
```javascript
const tl = gsap.timeline();
tl.to(".a", { x: 100, duration: 1 })
.to(".b", { y: 50, duration: 0.5 })
.to(".c", { opacity: 0, duration: 0.3 });
```
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.

How to install
mdr add bjornmelin/dev-skills/gsap-timeline@sha256:9e8efc6f9dafbc7fThe line at the top of this page pins the label git:20261015.c28ca52, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
