Headers and footers are just regular responsive sections. The default footer in most templates is a plain single column section, but you can use any column layout.
You can assign any section as the footer with these steps:
- create new section with footer content
- move section to the bottom of the page
- go to “Section Properties” and select “Assign as footer”
- you can assign more than one section as the footer
- header and footer sections are automatically inherited by all pages in the website
