Offset Ring Button
A ring springs out from the button's edge and hangs a small gap away, while the button gives a touch. It is an outline with a transitioned outline-offset, so the same rule doubles as the focus style.
Also known as: focus ring button, outline offset hover, ring on hover.

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