Conversely, moving objects (such as Dynamic HTML AP elements
flying across the screen) need a few seconds to complete their path. All of
Dreamweaver??™s Dynamic HTML animation effects use the Timeline feature to
manage this conjunction of movement and time.
Timelines can do much more than move an AP element across a Web page, however.
A timeline can coordinate an entire presentation: starting the background
music, scrolling the opening rolling credits, and cueing the voice-over narration
on top of a slideshow. These actions are all possible with Dreamweaver because,
in addition to controlling an AP element??™s position, timelines can also trigger any
of Dreamweaver??™s JavaScript behaviors on a specific frame.
This chapter explores the full and varied world of timelines. After an introductory
section brings you up to speed on the underlying concepts of timelines, you
learn how to insert and modify timelines to achieve cutting-edge effects. From
complex animations to slideshow presentations, you can do it all with
Dreamweaver timelines.
Because timelines are so intricately intertwined with AP elements
and behaviors, you need to have a good grasp of these
concepts. If you??™re not familiar with the topics of AP elements and behaviors, be
sure to read Chapters 11 and 12.
