title: How to add close button in SweetAlert pop up
body: <p>I have used the SweetAlert library for displaying a pop up in my application. This is my code</p>
  
  <pre><code>swal({
      title: "Are you sure?",
      text: "Test message?",
      type: "info",
      showCancelButton: true,
      focusConfirm: false,
      confirmButtonColor: "#DD6B55",
      confirmButtonText: "Yes",
      cancelButtonText: "No"
  }, function (isConfirm) {})
  </code></pre>
  
  <p>I need to add a close button in top right corner. Based on documentation, the close button available only for the SweetAlert2 library. </p>
  
  <p>Is it possible to add close button in the SweetAlert1 library?</p>
