The code above specifies the id and class attributes for the wrapper element and produces markup similar to this:

HTML
<body>
    <!-- The following is the wrapper element. -->
    <!-- It is nested inside an element defined by the `container` property (`<body>` by default). -->
    <div id="elementId" class="dx-overlay-wrapper dx-popover-wrapper class-name" ... > 

        <!-- The following element contains component content. -->
        <div class="dx-overlay-content">

            <!-- The following element displays content specified in the `contentTemplate`. -->
            <div class="dx-popup-content" ... >
                <!-- ... -->
            </div>
