Behaviors are the result of some action, such as loading a Web page.
Once the page is loaded and the event takes place, it triggers an action, such as playing a sound, calling a URL or displaying a popup message. For more complex, time-based actions, Dreamweaver includes a timeline for scripting events on the page. By dragging a layer onto the timeline and placing key points in the right places, a user can animate a layer and associate it with various events. A floating navigation bar could float onto the page, for example, and then play a sound file when it reaches a certain location. Frames palette and properties inspector.
