All the combination effects are based on the five Core Effects, and are thought of as examples to allow you to write your own effects.

Additionally, there’s the Effect.toggle utility method for elements you want to show temporarily with a Appear/Fade, Slide or Blind animation.

Effect.toggle uses any of the following pairs:

Toggle Parameter Appears With Disappears With
Appear Effect.Appear Effect.Fade
