<paper-dialog>
<paper-dialog> is a dialog with Material Design styling and optional animations when it is
opened or closed. It provides styles for a header, content area, and an action area for buttons.
You can use the <paper-dialog-scrollable> element (in its own repository) if you need a scrolling
content area. To autofocus a specific child element after opening the dialog, give it the autofocus
attribute. See PaperDialogBehavior and IronOverlayBehavior for specifics.
For example, the following code implements a dialog with a header, scrolling content area and
buttons. Focus will be given to the dialog-confirm button when the dialog is opened.
<paper-dialog>
<h2>Header</h2>
<paper-dialog-scrollable>
Lorem ipsum...
</paper-dialog-scrollable>
<div class="buttons">
<paper-button dialog-dismiss>Cancel</paper-button>
<paper-button dialog-confirm autofocus>Accept</paper-button>
</div>
</paper-dialog>Styling
See the docs for PaperDialogBehavior for the custom properties available for styling
this element.
Animations
Set the entry-animation and/or exit-animation attributes to add an animation when the dialog
is opened or closed. See the documentation in
PolymerElements/neon-animation for more info.
For example:
<script type="module">
import '@polymer/neon-animation/animations/scale-up-animation.js';
import '@polymer/neon-animation/animations/fade-out-animation.js';
</script>
<paper-dialog entry-animation="scale-up-animation"
exit-animation="fade-out-animation">
<h2>Header</h2>
<div>Dialog body</div>
</paper-dialog>Accessibility
