Pixel Art Toggle Switch
An 8-bit switch drawn in square pixels: box-shadow borders leave the corners notched, and the knob hops across in four steps() instead of sliding, like a menu toggle in an old console game.
Also known as: 8 bit toggle switch, pixel game switch css, retro game toggle.

}Customizing this snippet
- Color: set
--tgl-coloron the element or a parent. Currently previewing#3b82f6. - Size: set
--tgl-size. Every other dimension is inem, so the whole thing scales together. Currently previewing24px. - Speed: change the duration on the
transitionoranimationshorthand. Staggered delays are relative, so they keep their rhythm. - Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
