Gradient Radio Button
A conic gradient ring cut out with a radial mask. Unpicked rings rest in grayscale; the chosen one blooms into color, turns half a circle and a matching gradient dot spins in.
Also known as: gradient radio button css, colorful radio button css, conic gradient radio.

}Customizing this snippet
- Color: set
--rad-coloron the element or a parent. Currently previewing#3b82f6. - Size: set
--rad-size. Every other dimension is inem, so the whole thing scales together. Currently previewing18px. - 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.
