Content Objects
The primary content objects are Page Fields, Site Fields, and Maxlets. The term Content refers to your text, HTML, images, etc.
There are three types of Page Field: Heading, Text, and Image. Heading fields are single line Text-HTML fields, and Text fields are multi-line Text-HTML fields. All Page Fields are tied to a single page. Page Fields are edited with the Field Editor.
Site Fields are similar to Page Fields, in that they are edited using the Field Editor. However, they are tied to the entire site rather than to a single page.
