What problem does it solve? Interfaces without motion feedback feel unresponsive and disconnected. This Skill provides concrete patterns for adding functional UI motion — hover/press feedback, toggles, toasts, drawers, list reordering, and shared-element transitions — using Framer Motion (motion/react) or pure modern CSS, with correct timing, easing, and accessibility. ## Core Features & Use Cases - Gesture and spring animations: whileHover/whileTap press feedback, spring tuning (stiffness/damping), and enter/exit animations with AnimatePresence. - Layout and shared-element transitions: the layout prop for reordering and resizing, layoutId for magic-move transitions, and Reorder for drag-to-sort lists. - Pure CSS path: @starting-style for enter animations, transition-behavior: allow-discrete for animating to/from display:none, popover/dialog exit animations, and @property for animatable custom properties. - Use Case: You need an animated like button and a toast stack that slides in and collapses smoothly. The Skill gives you the AnimatePresence popLayout pattern, spring defaults, and a reduced-motion guard, delivered as one standalone HTML file. ## Quick Start Ask the AI to build an animated toggle switch with press feedback and a toast notification as a single standalone HTML file using Framer Motion from CDN.
