count-up

A number that animates up to its target on enter. Part of motion-anything; obeys MOTION-SPEC.md.

When to use it

Stat / metric blocks; drawing the eye to one impressive figure.

When NOT to use it (restraint)

Precise values the reader must read exactly mid-animation.
Many counters firing at once — pick the one that matters.

How to apply

Copy count-up.css and count-up.js and link them.
Mark numbers: <span data-count="10000" data-count-suffix="+">0</span>

(optional data-count-prefix="$", data-count-duration="900").

Accessibility & performance

prefers-reduced-motion: final value shown immediately. Tabular figures keep width steady.
