What problem does it solve? Writing correct GSAP animations requires knowing the right tween methods, transform aliases, easing names, and accessibility patterns; this Skill provides the official core API guidance so generated animation code follows GSAP best practices. ## Core Features & Use Cases - Core Tween Methods: Covers gsap.to(), from(), fromTo(), and set() with correct vars like duration, delay, ease, stagger, overwrite, and callbacks. - Transforms & Easing: Documents transform aliases (x, y, scale, rotation, xPercent), autoAlpha, svgOrigin, directional rotation, and the full built-in ease catalog plus CustomEase. - Responsive & Accessible Animation: Uses gsap.matchMedia() for breakpoints and prefers-reduced-motion so animations revert cleanly and respect user accessibility settings. - Use Case: When a user asks to animate a card grid entrance in React with staggered timing and reduced-motion support, this Skill produces gsap.to() code with stagger, autoAlpha, and a matchMedia guard. ## Quick Start Ask the AI to animate a set of elements with GSAP, for example staggering list items into view with a power3 ease and reduced-motion support.
