Agent prompt

Use Scale for a UI fragment: Scale helps express space, depth, and object state changes. Animate transform and opacity, keep the duration at 420ms, use 34px 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 express space, depth, and object 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 Scale on a card, list item, or lightweight panel.
  • Tune duration, travel, delay, and curve until Scale 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, Scale removes travel, rotation, or looping and keeps a short fade or state comparison.
