SIDEBAR WIDGET AREA
The Sidebar widget area is to the right of the content. If you put widgets in to this area they will appear on all pages and posts, with the exception of pages that use the page without sidebar template. If there are no widgets the content area will center.
FULL WIDTH FOOTER WIDGET AREA
The footer widget area is one full width area. Anything you insert here will appear on every page and post of your site. This is a great place for Social Media links or image links to your portfolios.
FOOTER WIDGET AREAS
Below the full width footer widget are 3 horizontally stacked footer widget areas.
Like the sidebar widget, if there aren’t any widgets in these areas then nothing will appear but your site copyright.
