Outline Toggle Switch
An outline-only switch: a stroked track and a hollow ring for a knob. Turning it on recolors both strokes and floods the ring with your accent from the inside, with a faint glow around it.
Also known as: outline toggle switch css, border only switch, ghost 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.
