Visual filters are prepackaged effects behavior that allow Web authors to easily apply visual effects to their content.

Transitions are time-varying filters that create a change from one visual state to another.

By combining filters and transitions with basic scripting, authors have a powerful tool for creating visually engaging and interactive documents.
