(elem, el)

    }

    function isHidden(elem, el) {
        // isHidden might be called from jQuery#filter function;
        // in that case, element will be second argument
        elem = el || elem;
        return jQuery.css(elem, "display") === "none" || !jQuery.contains(elem.ownerDocument, elem);
    }

    // NOTE: we've included the "window" in window.getComputedStyle
    // because jsdom on node.js will break without it.
