Description  

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.
