SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Web animation guidance prevents UI motion from feeling janky, slow, or distracting by standardizing easing, timing, performance, and reduced-motion behavior.

Core Features & Use Cases

Easing and timing decisions: chooses ease-out, ease-in-out, and ease based on whether elements are entering/exiting, moving, or hover-transitioning, with duration guidance for common UI patterns.
Production-grade animation practices: prioritizes animating transform and opacity, uses will-change to reduce jitter, and applies interruptible spring-style reasoning for gesture-like interactions.
Accessibility and interaction safety: adds prefers-reduced-motion fallbacks and avoids animating keyboard/navigation actions or hover states on touch devices.

Quick Start

Ask: "Help me design a smooth entrance and exit animation for a tooltip, including the right easing, duration under 300ms, and a prefers-reduced-motion fallback."

FAQPage Schema

How do I choose the right CSS easing and duration for UI animations like tooltips and modals?▼

CSS animation easing depends on interaction intent: use ease-out for entering elements, ease-in-out for moving elements, and ease for hover transitions. Keep tooltip and modal durations under 300ms to maintain a fast, natural UI feel.

What is the best way to prevent jank and ensure smooth performance in web animation design?▼

To prevent jank in web animation design, prioritize animating GPU-friendly properties like transform and opacity. Use will-change to reduce jitter and apply interruptible spring-style reasoning for gesture-like interactions to maintain smooth rendering.

How do I add prefers-reduced-motion fallbacks for accessible CSS animations?▼

Accessible CSS animations require prefers-reduced-motion fallbacks to disable or minimize movement for sensitive users. Avoid animating keyboard navigation actions and hover states on touch devices to ensure safe interaction across all accessibility contexts.

Does this web animation guidance work with existing UI libraries and microinteractions?▼

Yes, the web animation guidance applies to common patterns involving hover, tooltips, popovers, drawers, modals, and microinteractions across UI libraries. It standardizes performance tuning and motion design without requiring specific library dependencies.

When should I not use ease-in-out for UI motion design?▼

Avoid using ease-in-out for elements that are entering or exiting the screen, as it creates a sluggish start and end. Reserve ease-in-out for on-screen movement, applying ease-out for entrances and ease for hover transitions instead.
