CSS Team Avatar Row with Hover Spread

An overlapped row that fans open when you point at it, so a tight facepile becomes a legible team list without a click. Every avatar moves with translate — never margin — so the fan costs nothing in layout, each face carries a name tooltip, and :focus-within means a keyboard user gets exactly the same reveal as a mouse user.

Demo: CSS Team Avatar Row with Hover Spread
Source: https://codefronts.com/components/css-avatars/css-team-avatar-row-with-hover-spread/

An overlapped row that fans open when you point at it, so a tight facepile becomes a legible team list without a click. Every avatar moves with translate — never margin — so the fan costs nothing in layout, each face carries a name tooltip, and :focus-within means a keyboard user gets exactly the same reveal as a mouse user.

How this works

Fan with transforms, not margins. Animating margin re-runs layout on every frame and can bump neighbouring content. translate is compositor-only, and since each item already knows its index, the whole fan is one declaration:

.av-12__item{ transition:translate .32s cubic-bezier(.2,.8,.3,1); }
.av-12__row:hover .av-12__item,
.av-12__row:focus-within .av-12__item{
  translate: calc(var(--i) * var(--fan)) 0;
}

Stagger makes it feel deliberate. A tiny per-item delay turns a simultaneous slide into a cascade that reads as physical, without extending the total duration much:

.av-12__item{ transition-delay: calc(var(--i) * 18ms); }

Reserve the space the fan will need. The row keeps trailing padding equal to the total spread, so the expanded state never overflows, never triggers a horizontal scrollbar, and never overlaps the next element:

.av-12__row{ padding-inline-end: calc(var(--n) * var(--fan)); }

Keyboard parity is one selector. :focus-within on the row triggers the same spread, and the tooltip is revealed for whichever face has focus — so tabbing through the team is as informative as hovering it. On touch devices, where hover does not exist, the @media (hover: none) branch simply presents the row already spread.

Make it yours

  • Change the fan distance with --fan (0.5-1rem reads well at 3rem avatars). Larger fans need proportionally more reserved padding.
  • Fan in both directions by centring the row and using calc((var(--i) - var(--n)/2) * var(--fan)).
  • Swap the cascade for a simultaneous spread by removing the transition-delay — appropriate in dense toolbars where speed matters more than charm.
  • Add a slight rotate per item for a playing-card fan; keep it under 3deg or faces start looking tilted rather than fanned.
  • Combine with demo 11's +N chip: let the faces fan and pin the chip by giving it --i: 0.
  • For a click-to-expand variant, keep the transforms and drive them from a checkbox with :has() instead of hover.

Gotchas — read before shipping

  • Animating margins for the spread reflows the page every frame and can shift unrelated content — use translate.
  • Without reserved trailing padding, the fan overflows its container: expect clipped faces or an unwanted scrollbar.
  • Hover-only spread strands keyboard users. :focus-within is the fix, and each avatar must be focusable (a real link or button) for it to fire.
  • Tooltips that appear on hover but not focus fail WCAG 1.4.13; and a tooltip must not obscure the element it describes.
  • On touch there is no hover — either present the row spread with @media (hover: none) or make expansion a real tap target.
  • Staggering more than about 30ms per item makes an 8-avatar row feel sluggish; keep the total under 250ms.

Floor set by :has(), oklch(), backdrop-filter, text-wrap as this demo is written. The core technique itself goes back further — Chrome 105+.

Individual transform properties (translate — Chrome 104 / Safari 14.1 / Firefox 72), :focus-within (2017), calc() in transforms and the hover media feature are supported in all current browsers. :has() (Chrome 105 / Safari 15.4 / Firefox 121) drives the CSS-only theme toggle; oklch() sits behind @supports. No JavaScript.
