Gradient Pulse Text
A white-hot glow blooms out from the middle of the word in a quick double beat, then fades back to the accent. The bloom is a radial gradient whose radius is a registered percentage.
Also known as: pulsing gradient text, radial gradient pulse css, color bloom 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.
