the class ElementImpl method querySelector.

/**
 * {@inheritDoc}
 */
@Override
public Element querySelector(String selectors) {
    SelectorList selectorList = CSSUtilities.getSelectorList(selectors);
    List<Element> elem = new ArrayList<>();
    if (selectorList != null) {
        NodeListImpl childNodes = (NodeListImpl) getDescendents(new ElementFilter(null), true);
        childNodes.forEach(child -> {
            for (Selector selector : selectorList) {
                if (child instanceof Element && StyleSheetAggregator.selects(selector, child, null)) {
                    elem.add((Element) child);
                }
            }

    }
    return elem.size() > 0 ? elem.get(0) : null;
}
