const dialog
A dialog is an application window that is designed to interrupt the current processing of an application in order to prompt the user to enter information or require a response. See related alertdialog.
Authors SHOULD provide a dialog label. Labels may be provided with the aria-label or aria-labelledby attribute if other mechanisms are not available. Authors SHOULD ensure each active dialog has a focused descendant element that has keyboard focus.
