Tailwind Brass Periscope Lens Button

A brass periscope objective: a knurled bezel, an engraved focus scale, and a six-blade iris that opens on hover to reveal the glass — each blade a clipped triangle rotating about the optical centre, with a reflection sweep across the coated lens.

What changed in the port

Which parts became utilities, which stayed CSS, and why.

  • Utilities: the bezel, both masked rings, the barrel, all six blades' geometry and their scale-on-open, the flare sweep, the focusing rotation, the focus ring. CSS: the brass and glass gradients, and the two blade-rotation rules that compose the per-element --i.
  • The blade rotation is the collection's closing lesson. A per-element variable inside an arbitrary utility compiles to one shared rule — every blade would sit at the same angle. The same trap appeared on the shard button (demo 20), and both times the answer is a two-line CSS rule plus an inline index. Utilities are per-class; this data is per-element.
  • Six near-identical blade class lists is the honest cost, and it buys something real: each blade's open state (group-hover:scale-50) is visible on the blade, which is where someone tuning the aperture will look.
  • A11y fix from the CSS original: the button's own :focus-visible set outline:none and drew the ring on .bezel — correct — but the iris opened only on :hover and :focus-visible of the button, while the flare was hover-paired in the same selector. The port keeps them together and adds group-focus-visible: to both, so a keyboard user sees the full open-and-flare rather than a ring on a closed lens.

How this works

Six identical blades, one index each. The element carries its position; the shared rule turns the index into an angle:

<span style="--i:3" class="… group-hover:scale-50"></span>

.tb-51__blade { rotate: calc(var(--i) * 60deg); }
.tb-51 button:is(:hover,:focus-visible) .tb-51__blade { rotate: calc(var(--i) * 60deg + 44deg); }

The rotation stays CSS because it composes the per-element variable — rotate-[calc(var(--i)*60deg)] would compile one static rule shared by all six, which is the same trap as the shard button's angle.

The glass is three gradients: a broad coating tint, a hard specular crescent and a small catchlight. That combination is what reads as coated optical glass rather than a coloured circle.

The control is icon-only, so it carries an aria-label — the iris announces nothing.

Make it yours

  • Blade count: update the 60deg step and the number of blades together (360 / n).
  • Open amount is the added rotation plus the blade scale.
  • Coating tint: amber for a vintage uncoated lens, violet for modern multi-coating.
  • Remove the focus-scale ring for a cleaner modern optic.
  • The bezel's group-active:rotate-6 is the focusing gesture — drop it for a pure shutter.

Gotchas — read before shipping

  • Six clipped blades transitioning at once is fine; sixty is not.
  • clip-path on a rotated element clips in its own coordinate space — rotate the element, not the polygon.
  • Icon-only circular controls need an aria-label.
  • Radial knurl masks alias below ~4rem; widen the ticks at small sizes.
  • Keep the opening large enough at rest that users can tell what the control does.
