Rotate In
Spins in from minus 200 degrees at half size, unwinding and growing at once on an ease-out quint so the last few degrees crawl. A playful entrance for icons and badges.
Also known as: rotate in animation css, spin in animation css, rotate and scale in.

}Customizing this snippet
- Color: set
--kfa-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--kfa-size. Every other dimension is inem, so the whole thing scales together. Currently previewing16px. - Speed: change the duration on the
transitionoranimationshorthand. 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.
