CSS Avatar Group with Plus-N Overflow Count

A facepile that tells the truth about how many people are in the room: the final slot is a +N chip built to exactly the avatar's dimensions — same size token, same ring, same stack position — so the row's rhythm never breaks. The chip is a real <button> with the full count in its accessible name, and it expands the hidden members with pure CSS via a checkbox and :has().

A facepile that tells the truth about how many people are in the room: the final slot is a +N chip built to exactly the avatar's dimensions — same size token, same ring, same stack position — so the row's rhythm never breaks. The chip is a real <button> with the full count in its accessible name, and it expands the hidden members with pure CSS via a checkbox and :has().

How this works

The chip must be an avatar, dimensionally. Anything smaller reads as a mistake and anything larger breaks the row's baseline. Reuse the exact same tokens the faces use:

.av-11__more{
  inline-size: var(--size); aspect-ratio: 1;   /* same as a face */
  border-radius: 50%;
  box-shadow: 0 0 0 var(--sep) var(--panel);   /* same ring */
  margin-inline-start: calc(var(--size) * var(--dens) * -1);
  font-variant-numeric: tabular-nums;
}

The count is content, not decoration. "+12" on screen, the full sentence for assistive tech — and because it is a real control, keyboard users reach it in the natural tab order:

<label class="av-11__more">
  <input type="checkbox" class="av-11__toggle">
  <span aria-hidden="true">+12</span>
  <span class="av-11__vh">Show 12 more people in this project</span>
</label>

Expanding needs no JavaScript. The hidden members live in the DOM behind the hidden-style guard; when the checkbox is checked, :has() reveals them and the chip flips its label:

.av-11__extra{ display:none; }
.av-11__group:has(.av-11__toggle:checked) .av-11__extra{ display:block; }

Because the extras are real list items with the same overlap tokens, the row simply grows — no reflow of the surrounding layout, no measurement, no script. @starting-style fades each new face in from 0.6 scale where supported.

Make it yours

  • Cap the visible faces at 3 for dense tables, 5 for cards, 8 for a project header — only how many <li>s you render outside the extras group changes.
  • Style the chip as ink-on-surface (as here), or as a muted outline chip when the facepile sits inside a busy toolbar.
  • Swap the disclosure for a link to a members page if the full list belongs on its own screen — keep the +N geometry either way.
  • Put the chip first instead of last if your locale reads right-to-left; the logical properties already handle the flip.
  • For very large numbers, format with Intl.NumberFormat server-side (+1.2k) and keep the exact count in the accessible name.
  • Combine with demo 12's hover spread so the visible faces fan out while the chip stays put.

Gotchas — read before shipping

  • A chip that is not exactly avatar-sized is the most common facepile defect — reuse the size token rather than hardcoding a value.
  • Don't let the chip be a <div> with a click handler. A label+checkbox (CSS-only) or a <button> keeps it focusable and announced.
  • The visible "+12" is not a usable accessible name on its own; supply the sentence version in hidden text.
  • Proportional digits make the chip twitch between +9 and +12; use tabular-nums.
  • If the extras are removed from the DOM rather than hidden, the count can drift from reality — derive it from the same source as the list.
  • Keep the chip's ring identical to the faces'; a different ring width makes the row's end look misaligned even when the sizes match.

Browser support

:has() (Chrome 105 / Safari 15.4 / Firefox 121) drives the disclosure and the theme toggle. @starting-style and transition-behavior: allow-discrete (Chrome 117 / Safari 17.5 / Firefox 129) only add the reveal animation and are gated behind @supports — older browsers show the extra faces instantly. The facepile geometry itself works everywhere.
