<dialog>: The Dialog element

The HTML <dialog> element represents a dialog box or other interactive component, such as an inspector or window.

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.

Usage notes

• <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.

Examples

Simple example

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

Advanced example

This example opens a pop-up dialog box containing a form when the "Update details" button is clicked.
