Toggle switch component — mobile, brutalist style

Toggle switch UI component for websites and web apps, shown in Fernway, a fictional productivity product. Shows a list of on/off settings with labels and hints, switches on and off, a disabled switch, and every state (default, hover, focus-visible, on, disabled). Brutalist style: high contrast, Space Grotesk, uppercase headings, thick black borders and hard offset shadows. Comes with copyable HTML, CSS and a few lines of plain JavaScript (keyboard support and ARIA per the WAI-ARIA Authoring Practices), a live demo, and a DESIGN.md with light and dark colour tokens.

DESIGN.md

Component section (states, ARIA, keyboard)

## Component: Toggle switch

On and off settings that apply straight away, each with a visible label and a hint.

- **Pattern:** WAI-ARIA Authoring Practices, Switch (https://www.w3.org/WAI/ARIA/apg/patterns/switch/)
- **Roles and attributes:** Each switch is a <button role="switch"> with aria-checked, named by its visible label (aria-labelledby) and described by its hint (aria-describedby); a disabled switch uses the disabled attribute.
- **States drawn:** default, hover, focus-visible, selected, disabled
- **Focus:** a visible `:focus-visible` outline (3px solid text), never removed
- **Style knobs (brutalist):** border 2px, corners 0, shadow `3px 3px 0 var(--text)`, labels uppercase, tracked .02em
- **Motion:** transitions are short (≤160ms) and switched off under `prefers-reduced-motion: reduce`
- **Code:** HTML + CSS + a few lines of plain JavaScript (no libraries); colours come only from the tokens above, so light and dark both work

### Keyboard
- **Tab:** move between switches
- **Space / Enter:** turn the focused switch on or off
