Each content type has a default page layout. Each page’s layout can be overridden to fit your needs.

Additional Information About Panes
Drupal Lite uses the Panes modules for page layouts. All content that appears on the page is actually contained in Content Panes. When you are changing the layout of a page, the system will make a “best guess” as to where the panes should appear. If you’re familiar with the interface, you can drag-and-drop a pane from one region to another.
After selecting a page layout, I find it far easier to use the Customize This Page tool to rearrange the content in the regions. See more information about the Customize This Page tool.
