title: Create more serious looking jQuery error dialog?
body: <p>Is there a jQuery UI class you can use to create a more severe looking error dialog box than the one below?</p>
  
  <p><img src="https://i.stack.imgur.com/Ah3qg.jpg" alt="alt text"></p>
  
  <p>This is the HTML we use to create the dialog:</p>
  
  <pre><code>&lt;div style="display:none" id="div-dialog-warning"&gt;
      &lt;p&gt;&lt;span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"&gt;&lt;/span&gt;&lt;div/&gt;&lt;/p&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>And this is how we show it:</p>
  
  <pre><code>$("#div-dialog-warning").dialog({
      title: t,
      resizable: false,
      height: 160,
      modal: true,
      buttons: {
          "Ok" : function () {
              $(this).dialog("close");
          }
      }
  });
  </code></pre>
