iOS Toggle Switch
The iPhone settings switch: a pill track that fills with your accent and a white knob that glides across. Hold it down and the knob stretches toward the far side, just like iOS.
Also known as: ios toggle button css, iphone toggle switch css, apple settings switch.

}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.
