Buzz Out Hover Effect
A call button that buzzes like a phone on vibrate: fast little shifts and twists that fade out over three quarters of a second. For a buzz that never stops, set the iteration count to infinite.
Also known as: hvr-buzz-out, vibrate button css, phone ring hover.

}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.
