Like a footer on a document or report, a website footer contains information listed at the bottom of a page. Typically, the footer is the area that visitors expect to find the "fine print"—legal information, such as terms and conditions and privacy policies, but also links to FAQs, size guides, or contact information.
Access footer settings with the theme editor
Go to Customize > Sections > Footer to access the theme's Footer features.
Select a background style
Use the Background style dropdown to select either Dark or Default for the footer background.
Enable payment icons
Activate Enable payment icons to include these in the footer. You can enable and manage which logos appear through the Payments section of Settings.
Include a logo
If you want to show your logo in your store's footer (top, left corner), enable the Show logo in footer option. Then upload your Logo image (400 x 200px .PNG file), as well as an Inverted logo image.
Add content blocks
With Launch, you can add three optional types of content to your footer: Menus, Social media links, and Rich text. You can add up to four content blocks here.
Click Add content and choose the one you want to add.
