Panels allow you to create custom layouts for pages on your site. A panel is made up of multiple regions, or panes, that allow you to define areas on the page where content can be displayed.
In order to add a panel page to your site, the panels module must be enabled on the website.
NOTE: Before you create your panel, the content that you will use to populate the regions of your panel page may be created or already exist (i.e. pages or blocks). Be sure to make a note of the titles of each of the pages you will be pulling into the panel page.
