Form Factor is a miniature abstraction layer for view generation. Form Factor breaks the coupling between a view element and the structural markup generated, in order to make the generation more flexible. Instead of directly specifying the literal view to generate, Form Factor defers that to a template, which decides: (1) Structural markup to generate (2) stylesheets to include and (3) javascripts to include. Plugging in a different Form Factor template can be done with a single line of controller code, giving your site a different look and feel.
