Coin Flip Icon Hover
An icon button shaped like a coin that hops, spins two and a half turns and lands on its back, trading a star for a check. Stacked discs give the rim real thickness when it turns edge on.
Also known as: 3d coin flip css, spinning badge hover, flip coin button.

}Customizing this snippet
- Color: set
--hfx-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--hfx-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.
