<dialog>

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.

Summary

The HTML <dialog> element represents a dialog box or other interactive component, such as an inspector or window. <form> elements can be integrated within a dialog by specifying them with the attribute method="dialog". When such a form is submitted, the dialog is closed with a returnValue attribute set to the value of the submit button used.

The ::backdrop CSS pseudo-element can be used to style behind a <dialog> element, for example to dim inaccessible content whilst a modal dialog is active.

Attributes

This element includes the global attributes. The tabindex attribute must not be used on the <dialog> element.

open
Indicates that the dialog is active and available for interaction. When the open attribute is not set, it shouldn't be shown to the user.

Examples

Example 1

<dialog open>
  <p>Greetings, one and all!</p>

<script>
  (function() {
    var updateButton = document.getElementById('updateDetails');
    var cancelButton = document.getElementById('cancel');
    var favDialog = document.getElementById('favDialog');

    // Update button opens a modal dialog
    updateButton.addEventListener('click', function() {
      favDialog.showModal();
    });

    cancelButton.addEventListener('click', function() {
      favDialog.close();
    });

  })();
