Layout animation helps preserve visual continuity across state changes.

When an element's size or position changes, it animates to the new spot instead of snapping

Agent prompt

Use Layout animation for a UI fragment: Layout animation helps preserve visual continuity across state changes. Animate transform and opacity, keep the duration at 420ms, use 28px of visual amplitude, add a 0ms delay, use soft easing (cubic-bezier(0.23, 1, 0.32, 1)), and include a reduced-motion fallback.

Usage
  • Use it when you need to preserve visual continuity across state changes.
  • Good for low- or medium-frequency UI changes that should stay short, clear, and interruptible.
  • Copy the prompt or CSS and hand it to an agent for implementation.
Examples
  • Preview Layout animation on a card, list item, or lightweight panel.
  • Tune duration, travel, delay, and curve until Layout animation matches the surrounding interface.
Review notes
  • Prefer transform and opacity so motion stays off layout and paint work.
  • Keep UI motion under 300ms; frequent feedback should be shorter.
  • Avoid scale(0) and UI ease-in; use a physical starting point and a strong ease-out curve.
Reduced motion

Under reduced motion, Layout animation removes travel, rotation, or looping and keeps a short fade or state comparison.
