## PaperDialogBehavior
Use `PaperDialogBehavior` and `paper-dialog-shared-styles.js` to implement a Material Design
dialog.
For example, if `` implements this behavior:
```html
```
`paper-dialog-shared-styles.js` provide styles for a header, content area, and an action area for buttons.
Use the `` tag for the header and the `paper-dialog-buttons` or `buttons` class for the action area. You can use the
`paper-dialog-scrollable` element (in its own repository) if you need a scrolling content area.
Use the `dialog-dismiss` and `dialog-confirm` attributes on interactive controls to close the
dialog. If the user dismisses the dialog with `dialog-confirm`, the `closingReason` will update
to include `confirmed: true`.
### Accessibility
This element has `role="dialog"` by default. Depending on the context, it may be more appropriate
to override this attribute with `role="alertdialog"`.
If `modal` is set, the element will prevent the focus from exiting the element.
It will also ensure that focus remains in the dialog.
