What Adobe Edge can be used for
Generally, Edge can be used to create many of the same types of animations and interactions that we would have expected Flash Player to handle on the web in the mid to late 1990s. This includes the movement of visual objects across the stage and basic mouse interactions.
Note
Although it is now possible to create website intros, rich ads, and other motion content using a tool such as Edge, designers should be careful not to replicate the nuisances of the past. The web doesn't need more "Skip Intro" landing pages.
Web animation
Edge uses an all-new timeline for producing motion which borrows a lot from other applications such as Adobe After Effects. Through the use of keyframes along the Timeline, designers have very fine-grained control over many object properties and can easily enable easing algorithms, which provide an additional flair to animated content. In many ways, the Edge Timeline is superior to that found in other animation programs due to the level of control a designer is provided, and how richly control over these properties is enabled through the tools.
Interactive content
Edge is not just about making things move. The Edge Runtime also includes a robust API to enable interactivity through mouse, touch, and time-based Actions. These interactive commands can be applied to individual visible objects upon the stage, or used along the Timeline in the form of Triggers. Interactivity can modify aspects of the stage Timeline, modify the properties of other objects within an Edge project, or even invoke calls to content outside of the project.
