Float helps use continuous motion for waiting, liveliness, or ambient atmosphere.

A gentle, continuous up-and-down drift that makes a static element feel alive and weightless

Agent prompt

Use Float for a UI fragment: Float helps use continuous motion for waiting, liveliness, or ambient atmosphere. Animate transform and opacity, keep the duration at 1200ms, 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 use continuous motion for waiting, liveliness, or ambient atmosphere.
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 Float on a card, list item, or lightweight panel.
Tune duration, travel, delay, and curve until Float 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, Float removes travel, rotation, or looping and keeps a short fade or state comparison.
