Internal pages are more structured than basic pages. You can elect to use various features of the internal page, or to ignore them.
Internal pages have 6 regions.
Yellow is the banner region.
Orange is the sidebar.
Blue is the title of the page.
Purple is the introduction area.
Pink is the main body of the post.
Green is for the Spotlight and FYI boxes.
The purple introduction and green boxes are optional. If you leave these spaces blank, the zones will disappear.
