How this works

A visually-hidden checkbox drives the theme: the default state defines light-mode tokens (--surface, --ink, --line) on the card, and .pc-05__toggle:checked ~ .pc-05__card overrides the same variables with dark values. Every element reads from those tokens, so one boolean repaints the whole component.

The pill switch is pure CSS too — the knob is an absolutely-positioned circle that slides via transform:translateX() when the checkbox flips, on a springy cubic-bezier. Because only custom properties change, transitions on background and color cross-fade the two themes cleanly.

Make it yours

  • Retint either theme by editing the token block on .pc-05__card (light) or the :checked ~ .pc-05__card override (dark).
  • Make it follow the OS by wrapping the dark tokens in @media (prefers-color-scheme:dark) instead of the checkbox.
  • Change the knob travel with the translateX(23px) value to match a different switch width.
  • Speed up the theme cross-fade via the transition durations on the card.
  • Add a subtle knob glow by layering a coloured box-shadow on .pc-05__knob.
  • Persist the user's choice by mirroring the checkbox state to localStorage in your own build.

Gotchas — read before shipping

  • The checkbox must precede the card in source order for the ~ sibling selector to reach it.
  • Transitioning many properties at once can cause a brief flash of unstyled tokens on first paint — set an explicit default state.
  • A hidden checkbox still needs to be focusable and labelled for keyboard and screen-reader users.
