Show Password Eye Checkbox
A closed eye with lashes that opens when checked: the upper lid flips up into an arch, the lashes tuck away and the pupil pops in. Pair it with a line of JS that flips the password field's type.
Also known as: show password checkbox css, eye icon toggle css, password visibility icon.

}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.
