Screen transition behaviors let you add animated transitions between screens. To add a transition using a behavior, you attach the behavior directly to a screen.
You can select the direction of a transition: In plays the animation as the screen first appears in the document; Out plays the animation as the screen disappears from the document. You can also specify the duration in seconds.
Easing options let you modify the transition to achieve different effects.
Some transitions have additional parameters that you can modify. Parameters appear in the Transitions dialog box when you select the transition.
Follow these guidelines when adding transitions:
For most situations, the In option is recommended.
Use the In option when applying a transition that uses the on(reveal) event.
Use the Out option when applying a transition that uses the on(hide) event.
Do not add an Out transition immediately before an In transition in a presentation.
To attach the same transition to all children of a given slide, attach the single transition to the on(revealChild) or on(hideChild) event of the parent, rather than duplicating the transition on all child slides.
