Row Content - Footer
The Footer element/section is a "template" slot which affects all pages. This is noted with a red warning banner in the Website Editor Sidebar.
The "Contact Us" details use the Organization's Contact Details information as the default values although each can be overridden as needed.
The "Connect With Us" area shows icons for each of the social media sites you provide details for. See Social Media Links for more details.
The "Connect With Us" section will only be displayed if at least one Social Media Link has been saved for the Organization.
This toggles the general style of the footer to better work with "Light" or "Dark" Website Theme.
Also see Common Element Actions for more details on managing the Footer.
