Space and Separator
Space
Spaces allow you to create empty vertical space on the page. You can adjust the height by either clicking and dragging the element itself on the page or by manually setting the height (in pixels) in the editing sidebar.
Separator
Separators create a separator line or hard rule across the page to separate sections of content. From the left sidebar you can adjust the thickness of the line, its width (relative to the page or column) and its color.
