Float

Drifts up and down in a slow, even rhythm, and its shadow stays behind on the ground and softens as it rises. Good for hero art, app icons and empty states. Three second ease-in-out loop.

Also known as: floating animation css, css animation up and down loop, levitate effect.

Customizing this snippet

  • Color: set --kfa-color on the element or a parent. Currently previewing #3b82f6.
  • Base size: set --kfa-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 16px.
  • Speed: change the duration on the transition or animation shorthand. Staggered delays are relative, so they keep their rhythm.
  • Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
