     * Every element with an associated tooltip must have the "tooltip" class.

     * For simple tooltips, a title attribute is enough.
     *   Example: <span class="tooltip" title="This is a tooltip">...</span>
     *
     * For tooltips containing HTML markup:
     *   1. Create a container with a unique id and the class "tooltip-content" (so that it's hidden by default)
     *   2. Give the element that triggers the tooltip a class with the format "ttid-<id_of_tooltip_content_container>"
     *
     *   Example:
     *      <span class="tooltip ttid-foo-bar">...</span>
     *      <div id="foo-bar" class="tooltip-content">
     *          <p>All HTML in here will be hidden by default.</p>
