CSS Selector Level 4 » Matches-any pseudo-class

This pseudo-class is called matches-any pseudo-class and takes a selector list as argument. It lets you create sets of selectors by instituting groups which match all included selectors. Other pseudo-elements can't be represented with this pseudo-class, so e.g. negations may not be nested like this invalid example: E:is(:is(F)). Please note this selector was previously named :matches().

# Syntax

Copy
:is(selector1[, selector2,]) {
    /* declarations */
}

# Example

Copy
section h1, article h1, aside h1 {
    color: red;
}

/* Is the same as */

:is(section, article, aside) h1 {
    color: red;
}

/* Working, prefixed examples. Note: Mozilla and WebKit uses their own syntax :-prefix-any */
:-moz-any(section, article, aside) h1,
:-webkit-any(section, article, aside) h1{
    color: red;
}

This example will select all h1 headings which are childs of section, article, aside grouped by the :is selector.
