Matches an input element when its value has been automatically filled by the browser (like an address or credit card). It's useful for overriding the browser's default yellow background in autofilled fields.
Quick example
input:autofill {
/* Change the default yellow background to a subtle purple shadow */
-webkit-box-shadow: 0 0 0px 1000px #f5f3ff inset;
