SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

UI motion is often inconsistent or distracting, which can hinder usability. This skill provides a framework to apply animation principles to make interactions feel natural and purposeful.

Core Features & Use Cases

Apply a structured set of easing options (ease-out, ease-in, ease-in-out, linear) to match interaction intent.
Classify and implement motion durations (micro, short, medium, long) to align with interaction priority like button states, tooltips, page transitions, and complex choreographies.
Use motion principles (purposeful, natural, choreographed, interruptible) to design entrance, exit, emphasis, transition, and loading animations across web and mobile interfaces.
Best practices include accessibility considerations (prefers-reduced-motion) and performance tips (transform and will-change).

Quick Start

Apply a simple entrance animation to a new onboarding tooltip using ease-out with a 200ms duration.

FAQPage Schema

How do I choose the right easing and duration for UI animations?▼

Match easing and duration to interaction intent: use ease-out with 200ms for entrance animations like tooltips, scale duration from micro to long based on priority, and apply ease-in-out for symmetric state changes.

What are the core principles for designing natural UI motion?▼

Core UI motion principles require animations to be purposeful, natural, choreographed, and interruptible, ensuring transitions and micro-interactions communicate clear intent across web and mobile interfaces without distracting users.

How do I apply consistent animation principles across different UI elements?▼

Apply a structured framework classifying motion durations and easing options to align with interaction priority, categorizing animations into entrance, exit, emphasis, transition, and loading types for consistent web and mobile interfaces.

Does this UI motion framework support accessibility requirements?▼

Yes, the framework includes accessibility considerations like prefers-reduced-motion, ensuring UI motion adapts to user settings while maintaining performance using CSS properties like transform and will-change.

When should I use ease-in versus ease-out for web and mobile transitions?▼

Use ease-out for entrance animations where elements enter the viewport, and ease-in for exit animations, while linear easing works best for loading animations requiring continuous, uninterrupted visual feedback.

What is the best way to structure micro-interaction timing for modals and tooltips?▼

Structure micro-interaction timing by classifying durations into micro, short, medium, and long categories, applying 200ms ease-out for tooltips and scaling up to long durations for complex modal choreographies.
