What is the recommended easing for entering elements?

It recommends using ease-out (like quad or cubic) for entering elements to create an immediate, responsive feeling as the element decelerates into place.

How does this skill improve animation performance?

It identifies and replaces layout-triggering properties with transform and opacity, which skip the browser's layout and paint stages to run directly on the GPU.

Does it support React-specific animation libraries?

Yes, the skill provides specific patterns for Framer Motion and React Spring, including how to handle hardware acceleration and reduced motion hooks.

How does it handle accessibility?

It proactively suggests the 'prefers-reduced-motion' media query for every animation to ensure users with vestibular disorders can safely navigate your site.

When should I use spring animations instead of CSS transitions?

Springs are recommended for drag interactions, playful UI, or gestures that may be interrupted mid-motion, as they maintain natural momentum better than fixed durations.

Design Tools

Designs and implements high-performance, purposeful web animations using industry best practices for easing, timing, and accessibility.

This skill provides Claude with a comprehensive framework for creating professional-grade web motion based on the principles of Emil Kowalski's 'Animations on the Web.' It guides the selection of optimal easing functions—such as prioritizing ease-out for entering elements—calculates appropriate durations for micro-interactions versus modal transitions, and enforces performance optimizations by prioritizing GPU-accelerated properties like transform and opacity. Crucially, it ensures every animation includes accessibility support via media queries and handles complex scenarios like spring physics and gesture interruptibility to create interfaces that feel responsive and natural.

Key Features

01Performance-first implementation focusing on GPU-accelerated CSS properties to ensure 60fps motion.

030 GitHub stars

04Comprehensive accessibility integration including prefers-reduced-motion and touch-specific styling.

05Automated animation reviews using standardized comparison tables for clear optimization feedback.

06Context-aware easing selection guidance for entrances, exits, movements, and hover states.

Use Cases

01Refining clunky or 'janky' UI transitions to make them feel smoother and more responsive.

02Designing complex, interruptible gesture-based interactions using natural spring physics.

03Implementing accessible modal, drawer, or dropdown animations that respect system motion settings.
