Use Fade in / Fade out for a UI fragment: Fade in / Fade out 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.

- 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.
- Preview Fade in / Fade out on a card, list item, or lightweight panel.
- Tune duration, travel, delay, and curve until Fade in / Fade out matches the surrounding interface.
- 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.
Under reduced motion, Fade in / Fade out removes travel, rotation, or looping and keeps a short fade or state comparison.
