## JavaScript
```js
/* No JavaScript — a hard bottom box-shadow stem gives key depth, :active sinks the cap 3px, and :checked backlights icon + accent ring. */
```

How this works

The key is an sr-only checkbox followed by a 56px keycap span. Depth comes from a hard 6px bottom box-shadow stem plus a soft drop shadow; pressing the label (:active on the label, so the whole hit area drives it) translates the cap down 3px and collapses the stem to 2px — the key visibly bottoms out.

The latched state restyles three layers via :checked ~: the cap ground shifts to a green-black, the bell icon un-grayscales and scales to 1.15, and an absolutely-positioned ring span (inset −4px) lights its border with an accent glow. The icon is an inline SVG on currentColor, so state color changes are one property.

Make it yours

  • Retint the accent through --tgl-28-accent — ring, glow and icon all follow.
  • Deepen the travel by raising the 6px stem shadow and the :active translateY together.
  • Swap the bell SVG for any 24×24 stroke icon — it inherits currentColor.
  • Add navigator.vibrate(8) on change for real haptics (see demo 08).

Gotchas — read before shipping

  • Keep the press on the LABEL's :active, not the input's — sr-only inputs never receive :active from pointer clicks.
  • The stem shadow must be solid (zero blur) or the key reads as floating, not seated.
  • Icon state uses filter:grayscale — cheap, but keep it off the animation path; only the transform animates per press.
