Templates should use a single root element with a sensible CSS class
Wikipedia content is largely unstructured. One means of providing presentation hints for optimal parsing and display is to ensure that templates have only one outermost HTML element and that that element has a unique CSS class name shared across wiki languages. This can dramatically help software such as the mobile website, the Content Service, and the native Android and iOS apps to identify content properly.
