Spin Icon Button: CSS Hover Effect

Spin Icon Button

A settings cog that turns a half rotation on hover and turns back when you leave. A transition on transform, so the return trip is as smooth as the outbound.

Also known as: rotate icon hover, settings cog hover.

Customizing this snippet

Color: set --hfx-color on the element or a parent. Currently previewing #3b82f6.
Base size: set --hfx-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 16px.
Speed: change the duration on the transition or animation shorthand. 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.
