adobeOverview
sp-dialog displays important information that users need to acknowledge. They appear over the interface and block further interactions. When used directly the sp-dialog element surfaces a slot based API for deep customization of the content to be included in the overlay.
Note: the sp-dialog element is a component that is used to create a dialog layout. For modal and popover behavior, it should be used within a component that manages the overlay state.
Usage

import '@spectrum-web-components/dialog/sp-dialog.js';When looking to leverage the Dialog base class as a type and/or for extension purposes, do so via:

</sp-dialog>Behaviors
Use the dialog with an overlay to create a dialog that appears over the current page. The dialog manages several behaviors:
- Animation of the dialog content when opening/closing
- Focus management when the dialog opens
- Event handling for closing the dialog

</overlay-trigger>Receives focus
The receives-focus attribute can be used to control whether the dialog should receive focus when it is opened. Leverage the type="modal" and receives-focus="auto" settings in the Overlay API to ensure that focus is thrown into the dialog content when opened and that the tab order will be trapped within it while open.
The receives-focus attribute on overlay-trigger has three possible values:
auto(default): Focus will automatically move to the first focusable element in the dialogtrue: Forces focus to move to the overlay contentfalse: Prevents focus from moving to the overlay
For accessible dialogs, always use receives-focus="auto" or receives-focus="true" to ensure keyboard users can interact with the dialog content.
