    <div id="container" class="widget-container">
      <h4 class="widget-header">Containment</h4>
        <!-- rzContainment could be a CSS selector string, 'parent' or an Element object -->
        <div
          ngResizable
          [rzAspectRatio]="true"
          class="resizable-widget"
          rzContainment="#container"
