Thumbs Up Like Icon Hover
A thumbs up that dips back, then flicks up with overshoot and floats a +1. The anticipation comes from a back-in-out cubic-bezier on one transition, so leaving is animated too.
Also known as: like button animation css, thumbs up hover, upvote icon animation.

}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.
