Agent prompt

Use Pop in for a UI fragment: Pop in helps users understand how content appears or leaves the interface. 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 help users understand how content appears or leaves the interface.
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 Pop in on a card, list item, or lightweight panel.
Tune duration, travel, delay, and curve until Pop in 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, Pop in removes travel, rotation, or looping and keeps a short fade or state comparison.
