Agent prompt

Use Skeleton / Shimmer for a UI fragment: Skeleton / Shimmer helps make information changes and visual details feel more refined. 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 make information changes and visual details feel more refined.
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 Skeleton / Shimmer on a card, list item, or lightweight panel.
Tune duration, travel, delay, and curve until Skeleton / Shimmer 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, Skeleton / Shimmer removes travel, rotation, or looping and keeps a short fade or state comparison.
