Ripple Text Effect
A ripple spreads from the middle letter outward, each letter swelling and brightening as the ring passes. Each span carries its distance from the center, which sets its delay.
Also known as: center out text animation, scale wave letters, pulse ripple 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.
