Padlock Lock Checkbox
A padlock drawn with two spans: unchecked, the shackle swings open on its left leg; checked, it snaps shut with a small clunk and the body fills with the accent. Good for locking layers or files.
Also known as: lock unlock checkbox css, padlock toggle css, lock icon animation css.

}Customizing this snippet
- Color: set
--chk-coloron the element or a parent. Currently previewing#3b82f6. - Size: set
--chk-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.
