title: jQuery add CSS Class to bootbox Modal Dynamically
body: <p>I am using the jQuery plugin called Bootboxjs for my modals.</p>
  
  <p>This is how I run the code:</p>
  
  <pre><code>bootbox.dialog({
      title: '&lt;i class="fa fa-thumbs-up"/&gt;&lt;/i&gt;&amp;nbsp;&amp;nbsp;View Likes',
      buttons: {
          close: {
              label: '&lt;i class="fa fa-times"&gt;&lt;/i&gt;&amp;nbsp;&amp;nbsp;Close',
              className: "btn-danger",
              callback: function() {
  
                  // Close the modal
  
              }
  
          }
      },
      message: '&lt;span name="getLikesResults"&gt;&lt;/span&gt;'
  });
  </code></pre>
  
  <p>I am making a plugin for a project and I don't want this to affect existing modal styles but I need to make this specific modal scrollable when the content reaches the max height.</p>
  
  <pre><code>.modal .modal-body {
      max-height: 420px;
      overflow-y: auto;
  }
  </code></pre>
  
  <p>How could I apply the above CSS to just this <code>bootbox</code> modal?</p>
