This page will show you the default layouts (known as "Focus" elements) that can be added to any page and used as a basis on which to create or add to a page.
To explain, each "Focus" element is a collection of "Modules" that have been pre-arranged to give a starting point design layout - a bit like a template.
"Modules" are single building-block elements, such as a text box, an image box, a contact form, a video box, a slideshow, etc., etc.
By looking at this page, you can get an idea of what a certain "Focus" template will look like. You can add as many Focus collections or Modules to any page and rearrange them as you wish by dragging and dropping, resizing as needed, changing the sample photos they add, etc, etc.
