This widget shows most of the common UX elements in a community – it can be used by designers/developers to review base markup/styling for a new or existing site and test/validate styling changes. The widget can be placed on any page to show the base format styling in that context.
The below is an example of the results of the widget placed on its own Community page in an OOTB Community 12 site.
