SimpleModal is a lightweight jQuery Plugin which provides a powerful interface for modal dialog development. Think of it as a modal dialog framework. SimpleModal gives you the flexibility to build whatever you can envision, while shielding you from related cross-browser issues inherent with UI development.

Styles can be applied through external CSS, the options object, or both. The CSS options for the modal overlay, container, and data elements are: overlayCss, containerCss and dataCss, all which take a key/value object of properties.
