title: Alertify JS Center dialog window
body: <p>Is there a way to center the dialog windows of the Alertify Js plugin? <a href="http://alertifyjs.com" rel="nofollow noreferrer">http://alertifyjs.com</a></p>
  
  <p>I have seen there is a property called position, but it does not support center position.</p>
  
  <p>Thank you all.</p>
