11 Apr 2012, 16:17:07F2F Notes: Gottfried mention replacement for active value:
@media screen and (high-contrast) /* any high-contrast value */
Instead of:
high-contrast-adjust: auto | none;
Consider:
high-contrast-noadjust: auto | all | property list;
example: okay to override :focus pseudo-class 'outline' property on this element, but not okay to override 'background-image' property:
.replaced {
outline: solid 1px red;
background-image: url(foo.png);
high-contrast-noadjust: background-image;
}
