Footer areas are found on the Dashboard under Appearance/Widgets. A screen capture of the Widgets list appears at the bottom of this page.
The ACLT site uses Footer 1, Footer 2, Footer 3, and Footer 4. I found that centering the content worked best for resizing to smaller media.
The copyright line below the footers is edited from the dashboard under Genesis/Simple edits. The text that appears on the pages comes from the “Footer Output” box. The text includes code to call up the copyright symbol and the current year.
