# paper-dialog-behavior `paper-dialog-behavior` implements behavior related to a Material Design dialog. Use this behavior and include `paper-dialog-common.css` in your element to implement a dialog. `paper-dialog-common.css` provide styles for a header, content area, and an action area for buttons. Use the `<h2>` tag for the header and the `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. For example, if `<paper-dialog-impl>` implements this behavior: ```html <paper-dialog-impl> <h2>Header</h2> <div>Dialog body</div> <div class="buttons"> <paper-button dialog-dismiss>Cancel</paper-button> <paper-button dialog-confirm>Accept</paper-button> </div> </paper-dialog-impl> ```
