Flip Toggle Switch
The knob is a coin with OFF on one face and ON on the other: it rolls across the track and flips over in 3D on the way, landing with a small wobble. Uses preserve-3d and backface-visibility.
Also known as: 3d flip toggle css, coin flip switch, flip card toggle 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.
