Ripple In Hover Effect
Two rings close in from outside the button, one after the other, and fade as they land on its edge while the button takes a light tint. The reverse of a ripple: it pulls the eye in.
Also known as: hvr-ripple-in, converging ring hover, ring closes in on 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.
