One radio drawn three ways, small, medium and large. Every part is in em, so each size is just a font-size on the row, and a subgrid keeps the size labels and options lined up in columns.
Also known as: css radio button size, change radio button size css, small and large radio buttons, radio button sizes.

}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.
