Lock Unlock Toggle
A padlock knob: unlocked, the shackle is lifted and tilted open; lock it and the knob slides over, then the shackle drops shut with a springy click. The shackle turns from its left leg.
Also known as: padlock toggle css, lock switch animation, locked unlocked 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.
