When should I use CSS animations over a JavaScript library?

CSS animations are ideal for UI transitions, looping effects, and scroll-linked motion that don't require complex physics or fine-grained playback control.

How does the skill handle animation timing?

It implements a standardized CSS custom property token system for durations and easing functions to ensure design consistency across an entire application.

Does this skill support web accessibility?

Yes, it mandates the use of prefers-reduced-motion media queries to ensure all animations respect user system preferences for reduced motion.

Why does this skill focus only on transform and opacity?

These properties are handled by the browser's compositor thread, which avoids expensive layout and paint cycles, ensuring animations maintain a smooth 60fps performance.

设计工具

Implements performant, accessible CSS animation patterns using GPU-accelerated properties and motion-sensitive design principles.

This skill provides a comprehensive framework for creating smooth, 60fps web animations by leveraging CSS transitions and keyframes while prioritizing performance and accessibility. It guides Claude to use GPU-accelerated properties like transform and opacity, enforces the use of design tokens for consistent timing, and ensures every animation respects user preferences via prefers-reduced-motion. It is particularly useful for building modern UI components, scroll-linked effects, and micro-interactions that don't require the overhead of JavaScript animation libraries.
