:matches() Pseudo-Class

:matches() is a new CSS pseudo-class that allows to save time by grouping selectors together:

:matches(article, div.section, section) h2 {
  font-size: 3em;
}

/* Is this equivalent of this: */
article h2, div.section h2, section h2 {
  font-size: 3em;
}

Here’s another example to bring home the point:

:matches(.main, p, div.my-stuff) :matches(h1, h2, h3, h4) {
  border: 2px dotted rgba(255,134,34,0.5);
}

/* Is this equivalent of this: */
.main h1,
.main h2,
.main h3,
.main h4,
p h1,
p h2,
p h3,
p h4,
div.my-stuff h1,
div.my-stuff h2,
div.my-stuff h3,
div.my-stuff h4 {
  border: 2px dotted rgba(255,134,34,0.5);
}

Lots of time saved typing all of this in this second example! This can really help make your CSS files smaller too.
