</div>About Dark Mode Toggle
Dark Mode Toggle is a checkbox built with transforms and layered shadows. Its stylesheet runs to 58 lines across 10 rules, declaring 25 distinct properties. It styles active and checked states explicitly, so the component responds to interaction rather than sitting still. Every format shown on this page is the same component, so you can take HTML, CSS and Tailwind depending on how your project is set up. Nothing is minified and nothing depends on a framework.
When to use
- Settings panels and forms, where state has to read at a glance, where a dark and light checkbox fits the surrounding design
- Repeated use across a page, since there is no animation to become tiring when several appear together
- Palettes built around yellow, blue and white, where this checkbox can be dropped in without retheming
- Places where one control is meant to be memorable, since 58 lines of CSS is a real investment for a single element
- Design systems, since the colours sit in custom properties and can be themed centrally
How it works
The base rule sets the shape with border-radius, display, height and position. Movement is done with transforms rather than by changing position or size, which is what keeps it smooth: transforms are composited and do not force the browser to lay the page out again. State changes are eased with a transition, so hovering does not snap. Colours are held in custom properties, so retheming means editing the variables at the top rather than hunting through the rules.
Accessibility
Built on a native <input> element, so keyboard focus and screen reader semantics work without extra attributes. No focus style is defined. Add one before shipping, or keyboard users lose track of position. That is one thing to fix before this ships in front of users.
Browser support
Everything this component uses has been supported across browsers for years, so no fallback is needed.
