Bouncing Rotating Words
Each word falls into the headline, squashes on impact, hops once and settles, while the old word drops out below. The squash is a scale on a bottom transform-origin, so the word lands on its baseline.
Also known as: bounce word swap, dropping words animation, squash and stretch text.

}Customizing this snippet
- Color: set
--txt-coloron the element or a parent. Currently previewing#3b82f6. - Font size: set
--txt-size. Every other dimension is inem, so the whole thing scales together. Currently previewing40px. - 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.
