Post Navigation module for Singular theme layouts (Themer)
The Post Navigation module is in the Post modules category, which appears only when you're editing a Singular-type theme layout in Theme Builder. It displays links to previous and next posts, in reverse chronological order.
On large and medium devices, the Previous post link is left-aligned, and the Next post link is right-aligned. On small devices, they are stacked.
The only settings available for the Post Navigation module are those on the Advanced tab, which means you can customize margins, responsive layout, visibility, animation, and assign an ID or class name.
