The footer appears at the bottom of every page on your website. Any edits you make are applied site-wide, so you only need to update it once. It's an important branding and navigation element, often containing contact details, social links, and secondary navigation.
Footer navigation and styling have moved. Your footer menu (the grouped links), footer layout, colours and width are now managed in the Navigation Manager, open it and switch to the Footer Menu tab, then use the styles wheel for Footer Styles. The footer content there also holds your Additional text and Copyright. The steps below apply to older footers edited directly in the page editor.
