Pulse Text
The text swells and relaxes on a slow beat. A single scale keyframe; use it on a call to action you want people to notice without moving anything across the screen.
Also known as: heartbeat text, throbbing text, scale pulse.

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.
