Page Templates
A page template is a maxlet which determines the layout of a page (preformatted pages have no template). There are two types of page template: Freeform and Static.
A Freeform template defines a backdrop over which absolutely postioned content is placed using the Freeform Page Editor. The backdrop is defined with HTML. Like any maxlet, the template may have additional properties for colors, fonts, etc., which can be altered once the template is customized.
A Static template defines an entire page layout: both backdrop and content positions. Generally, these maxlets have properties defining slots into which content objects can be selected.
Styles
Some page templates have a group of Style properties. Each style property controls the look of a particular class of object placed on the page. Styles give you a powerful mechanism to control how your entire page looks by modifying a small number of properties. Page template styles affect only maxlets, and not all maxlets use styles to control their look.
Styles are actually a special kind of maxlet known as a Set. A Set is just that, a set of properties. These properties are usually things like colors, fonts, border widths, etc., which determine how an object looks.
See Page Layout and Site Layout for information on selecting a template.
