Jack In The Box
Springs up out of nothing from its bottom edge, stretched tall and tilted, then wobbles left and right until it stands still. The pivot sits on the bottom center, like a toy on a spring.
Also known as: jackInTheBox animation, jack in the box css, pop up wobble entrance.

}Customizing this snippet
- Color: set
--kfa-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--kfa-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.
