Description #

sp-dialog-wrapper supplies an attribute based interface for the managed custmization of an sp-dialog element and the light DOM supplied to it. This is paired it with an underlay attribute that opts-in to the use of an sp-underlay element between your page content and the sp-dialog that opens over it.

Usage #

See it on NPM! How big is this package in your project? Try it on webcomponents.dev

yarn add @spectrum-web-components/dialog

Import the side effectful registration of <sp-dialog-wrapper> via:

import { DialogWrapper } from '@spectrum-web-components/dialog';

Accessibility #

An sp-dialog-wrapper element leverages the headline attribute/property to label the dialog content for screen readers. The headline-visibility attribute will accept a value of "none" to suppress the headline visually.
