Just as a page has a skin, Modules have containers. Containers control the look and feel of a single module. A container is a template that is applied to each module that determines the layout and general graphical design of the Module. A Container can be applied to a single Module, all Modules on a page, or all Modules in an entire site. Containers contain Module backgrounds, font properties, and editing links.
In addition, Containers also contain CMS controls that provide certain functionality to your site such as display of the Module title or provide a print link.
Containers are included with the skin package that your district selects and are designed to match the skin's color and layout.
