Open Closed Sign Toggle
A shop sign hanging from a nail: switch it and the board flips over in 3D from CLOSED to OPEN, then swings on its string and settles. Two faces with backface-visibility: hidden.
Also known as: open closed toggle css, flip sign switch, shop sign 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.
