+# matchesSelector helper
+
+[`matches`/`matchesSelector`](https://developer.mozilla.org/en-US/docs/Web/API/Element/matches) is pretty hot :fire:, but has [vendor-prefix baggage](http://caniuse.com/#feat=matchesselector) :handbag: :pouch:. This helper function takes care of that, without polyfilling or augmenting `Element.prototype`.
+
+``` js
+matchesSelector( elem, selector );
+// for example
+matchesSelector( myElem, 'div.my-hawt-selector' );
+```
+
