CSS Selector Level 4 » Specificity-adjustment pseudo-class

Similar to matches-any this specificity-adjustment pseudo-class represents an element that is represented by its arguments (as selector list) just with a specificity of zero. This is helpful whenever a general matching is used but simple overwrites should still be possible.


:something(selector1[, selector2,]) {
    /* declarations */


input:something(:not(:focus)) {
    background-color: #000000;

form input {
    background-color: #bbbbbb;

All inputs in this example should have a black background (except on focus) with a specificity of zero which means form input would already overwrite the selector due to a higher specificity.
