A toggle switch is an iOS-style binary controller where a thumb slides left/right on a track. Unlike checkboxes, it emphasizes immediate effect — settings change the moment you flip it. Perfect for notifications, themes, and permissions.
Key implementation: Slide the thumb via left property + transition: 0.3s. Add box-shadow for depth. Pure CSS version using :checked pseudo-class has better accessibility. Use class toggles, not inline style checks, for state.
Common pitfalls: Missing transition = instant jump. Wrong max left value = thumb overflows. Missing role="switch" for screen readers. Using style.background string comparison for state (unreliable).
Variants: ON/OFF text labels, three-position switch, square Material style, color-coded states, linked toggle groups.
