Square Toggle Switch
A switch with square corners and a square knob with grip lines, like a slider on a mixing desk. It snaps across on an ease-in-out curve for a mechanical feel. Tailwind version included.
Also known as: square toggle switch css, rectangular switch, flat square switch.

- 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.
