How this works

M3's defining trait is the state-carrying thumb: unchecked it's a small 16px dot in outline color resting 6px from the left of the 52×32 outlined track; checked it grows to 24px, deepens to the on-primary tone (#381e72 on a #d0bcff track) and moves to left:22px — the exact spec sum (48px inner − 24px thumb − 2px breathing room).

Growth and travel are separate transitions (width/height at 0.15s, left at 0.2s on the standard curve) so the thumb visibly swells as it arrives, matching the Material motion spec's emphasis. Track fill and border collapse to the same tonal color when checked, per M3.

Make it yours

Retheme with your own M3 tonal pair (track/thumb) — the geometry is spec-fixed.
Add the pressed 28px state with :active width/height rules.
Drop in a checkmark icon via a masked ::after (see demo 14).
Light-scheme variant: swap the four color values only.

Gotchas — read before shipping

The left-position math must track any resize: inner width − thumb − 2px; hardcoded 22px only works at spec size.
This variant animates width/height/left for spec fidelity on a 24px element — negligible, but demo 14 shows the transform-only approach if you're INP-strict.
Keep the 2px outline in the off state — it's M3's required affordance that the control is interactive.
