Grow Rotate Hover Effect
A coupon chip that grows and tips a few degrees on hover, on a spring curve that overshoots and settles. The dashed inner line is an outline with a negative offset, so it needs no extra markup.
Also known as: hvr-grow-rotate, rotate and scale on hover, tilt button 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.
