Share Button with Live Count Badge

A share control with the running total beside it. The figure uses tabular-nums so digits occupy identical widths and the badge never jitters as the number changes, a short scale pulse marks each increment, and counts above a thousand collapse to 1.2K. State lives in aria-pressed and every change is announced through a polite live region.

How this works

Tabular figures are why it looks stable. In a proportional font the digit 1 is narrower than 8, so a counter ticking from 1,199 to 1,200 physically resizes and shoves the layout beside it. One declaration fixes it for good:

.soc-08__count{ font-variant-numeric:tabular-nums; }

The pulse is a one-shot animation, not a class dance. Incrementing sets a data attribute; the keyframe runs once and an animationend listener removes the attribute so the next increment can retrigger it. No timers, no double-buffering, and nothing left in the DOM once the animation finishes.

Visual change is not an accessible event. A number swapping in place fires nothing for a screen reader. The button carries aria-pressed so its state is exposed, and a role="status" region announces the new total in words — the state is never carried by colour or motion alone.

The trap: reserving space for the badge. If the count arrives from an API after paint, the badge appears and pushes the button sideways. Give the badge a min-inline-size sized for your realistic maximum so the layout is stable before the first byte of data arrives.

Make it yours

  • Change the starting figure and the compact threshold in the formatter — swap 1000 for 10000 if you prefer full numbers longer.
  • Set --pulse-scale to tune how emphatic the increment feels.
  • Move the badge inside the button instead of beside it by moving one element in the markup.
  • Restyle the badge as a pill, a superscript, or a stacked block with a label underneath.
  • Feed the count from your API on load — the formatter and pulse are already decoupled from the click handler.
  • Remove the toggle behaviour and make the control fire-and-forget if your backend does not support un-sharing.

Gotchas — read before shipping

  • Without tabular-nums the badge visibly twitches on every increment, which is the single detail that makes a share counter feel cheap.
  • Removing and re-adding an animation attribute in the same frame does not restart the animation; wait for animationend or force a reflow.
  • A count that changes with no live region is silent to assistive technology — the visual pulse communicates nothing to a screen reader.
  • Sharing counts fetched per page view are a real performance cost; cache them server-side rather than firing a request per social channel.

Floor set by oklch(), color-mix(), text-wrap as this demo is written. The core technique itself goes back further — Chrome 111+.

font-variant-numeric and CSS animations are universal; the stated floor is color-mix() for the tinted surfaces, which falls back to the hex tokens declared first.
