Live Visitor Counter
A live pill says 1,284 viewing now: a green dot pings while the last two digits roll up or down to each new count, like a real-time analytics badge. Pure CSS digit strips and keyframes.
Also known as: live visitor counter css, people viewing now animation, real time counter css, odometer 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.
