Wobble Horizontal Hover Effect
The button shakes side to side a few times, each swing smaller than the last, then comes to rest. A one-shot keyframe on hover: the same motion a login form uses to say no.
Also known as: hvr-wobble-horizontal, shake button on hover, head shake hover css.

}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.
