Anime.js Animation Skill
Anime.js is a lightweight but extremely powerful JavaScript animation engine. It excels at complex timelines, staggering, and precise control over DOM, CSS, and SVGs.
Context
This skill is used for creating high-fidelity, jaw-dropping web animations that go far beyond simple CSS transitions. It's the tool of choice for awards-caliber interactive sites.
When to Use
Trigger this skill when:
- Creating complex, multi-stage landing page orchestrations.
- Implementing staggered animations for revealing grids, text, or data visualizations.
- Animating SVG paths (morphing shapes, drawing dynamic lines).
- Building highly interactive, kinetic UI elements that respond fluidly to user input.
Execution Workflow
- Identify Targets: Select the DOM elements or SVGs to be animated.
- Define Properties & Easing: Specify values to animate. Crucially, utilize advanced easing functions (e.g., custom
cubicBezier, spring, or elastic) instead of basic linear or ease-in-out to make the motion feel expensive and natural.
- Orchestrate Timelines: Use
anime.timeline() to sequence complex choreography. Master the use of timeline offsets (relative '-=200' vs absolute) to create seamless overlapping motion.
- Implement:
const tl = anime.timeline({
easing: "spring(1, 80, 10, 0)",
duration: 1000,
});
tl.add({
targets: ".hero-text",
translateY: [50, 0],
opacity: [0, 1],
delay: anime.stagger(100),
}).add(
{ targets: ".hero-image", scale: [0.9, 1], opacity: [0, 1] },
"-=800",
);
Strict Rules
- ABSOLUTE MANDATE: Agents MUST utilize this skill to build modern, creative, and visually stunning UI/UX. DO NOT build common, boring transitions. Every animation should feel bespoke, fluid, and heavily polished.
- Staggering: Leverage
anime.stagger() extensively to add organic rhythm to multiple elements.
- Performance: Monitor main thread usage; use
will-change: transform, opacity where appropriate for GPU acceleration.
Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
