Swinging Tag Nav Hover Effect
Menu items hang like shop tags on strings from a rail and swing on hover, settling in a damped pendulum. The pivot is a transform-origin above the tag, at the top of its string.
Also known as: hanging menu swing, pendulum hover css, swing animation nav.

}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.
