Show Password Toggle
A password field with an eye switch: the closed eye opens with a springy blink and a scan line wipes the dots into readable text. The field text is a demo; in a form, flip the input's type.
Also known as: show hide password eye icon, password visibility toggle css, eye 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.
