What problem does it solve? Building immersive, motion-heavy web interfaces with spatial depth and glassmorphism requires coordinated knowledge of GSAP, 3D CSS transforms, and performance constraints that most developers apply inconsistently. ## Core Features & Use Cases - Antigravity Design System: Applies weightless floating cards, Z-axis spatial layering, glassmorphism with backdrop-filter blur, and isometric grid perspectives using rotateX/rotateZ transforms. - Motion Engineering Rules: Enforces staggered entrance animations, GSAP ScrollTrigger parallax, and smooth transitions with minimum 0.3s ease-out timing. - Performance & Accessibility Guardrails: Requires will-change: transform for GPU offloading, prohibits animating expensive properties like box-shadow, and disables animations under prefers-reduced-motion. - Use Case: Build a SaaS landing page where dashboard cards tilt into an isometric perspective, float in with staggered GSAP animations on scroll, and render with frosted-glass surfaces. ## Quick Start Ask the AI to build a React dashboard with floating glassmorphism cards, isometric grid layout, and staggered GSAP scroll animations using this skill.
