SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

CSS animations often suffer from performance issues and accessibility gaps. This skill guides you to craft animations that are composited-only, leverage scroll-driven effects and view transitions, and include robust prefers-reduced-motion fallbacks to ensure smooth UX.

Core Features & Use Cases

  • Composited-only properties: transform, opacity, and certain filters to keep animations GPU-friendly.
  • Motion patterns: entrances, hover/focus states, and choreographed sequences using @keyframes, transitions, and the View Transition API.
  • Scroll-driven experiences: timeline-based animations that react to page scroll or viewport visibility while degrading gracefully on unsupported browsers.

Quick Start

Describe the animation you want (e.g., a button hover that fades in and slides up) and I will generate a composited-safe CSS animation with a reduced-motion fallback.

FAQPage Schema
What is the best way to create performant CSS animations for web interfaces?

Use composited-only properties like transform, opacity, and filters to keep CSS animations GPU-friendly. This approach ensures smooth UI motion design for entrances, hover states, and choreographed sequences without triggering performance issues.

How do I add scroll-driven animations that react to viewport visibility?

Scroll-driven animations use timeline-based effects that react to page scroll or viewport visibility. They degrade gracefully on unsupported browsers, ensuring the animation experiences remain functional across different environments.

How do I implement a fallback for prefers-reduced-motion in CSS animations?

Include robust prefers-reduced-motion fallbacks by defining alternate styles or disabling animations for users who request reduced motion. This ensures accessible UI motion design while maintaining the core functionality of the interface.

Can I use the View Transition API for choreographed entrance animations?

Yes, the View Transition API supports choreographed sequences and view-transition choreography for UI motion design. It works alongside @keyframes and transitions to create seamless state changes in web interfaces.

Why does my CSS animation cause layout jank during scroll reveals?

CSS animation jank often occurs when animating non-composited properties that trigger layout recalculations. Switching to composited-only properties like transform and opacity keeps the animations on the GPU and avoids main-thread blocking.
