Springy Text Animation
Each letter is wound down onto a spring, released, and bobs above and below its resting line with shrinking swings. The squash and stretch rides along with the motion, pinned to the baseline.
Also known as: spring animation text, elastic letters, boing letters css.

}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.
