SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

UI motion decisions can be inconsistent, inaccessible, or performance-heavy; this guide provides structured guidelines to design, implement, and review motion across interfaces.

Core Features & Use Cases

  • Clear motion philosophy for velocity, easing, and duration
  • Accessibility-first rules including prefers-reduced-motion and reduced-motion safe defaults
  • Practical patterns for CSS transitions, keyframes, and Framer Motion usage
  • Use cases such as onboarding tours, modal entrances, and interactive feedback

Quick Start

Follow these guidelines to design, implement, and review UI motion for accessibility and performance.

Frequently Asked Questions about ui-animation

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I make Framer Motion animations accessible with prefers-reduced-motion?

To make Framer Motion animations accessible, apply prefers-reduced-motion media query checks to disable or reduce motion. Use reduced-motion safe defaults and ensure animations are interruptible to satisfy accessibility requirements for users with motion sensitivities.

What is the best way to handle CSS transitions for performant UI motion?

The best way to handle performant CSS transitions is to animate transforms and opacity exclusively while following clear motion guidelines for velocity, easing, and duration. This approach prevents performance bottlenecks and maintains a smooth 60fps web interface experience.

How do I audit web interfaces for UI animation performance and accessibility?

Audit web interfaces for UI animation by checking speed, interruptibility, and prefers-reduced-motion support. Review CSS transitions and Framer Motion implementations to ensure they use transforms and opacity correctly while passing clear accessibility checks for reduced-motion preferences.

Does UI motion need to be interruptible for accessibility compliance?

Yes, UI motion must be interruptible to satisfy accessibility requirements. Motion guidelines dictate that interactive feedback, modal entrances, and onboarding tours should respond immediately to user input, ensuring animations do not trap focus or delay interaction for assistive technology users.

Can I use keyframes for onboarding tours without violating motion guidelines?

You can use keyframes for onboarding tours if you follow motion guidelines for velocity, easing, and duration while respecting prefers-reduced-motion. Ensure keyframe animations use transforms and opacity, remain interruptible, and provide reduced-motion safe defaults for accessibility.

Why does my UI animation cause layout shifts and performance issues?

UI animation causes performance issues and layout shifts when animating properties other than transforms and opacity. Following structured motion guidelines to exclusively animate transforms and opacity prevents browser recalculations, ensuring smooth, performant web interface motion.
