# Animating overlays

Animation is important for creating dynamic and compelling overlays. It defines how an overlay behaves when taken on-air or off-air, or sitting on screen.

The three methods of animating in Singular's Composer are:

* [Timeline animations](#timeline-animations)
* [Behavior animations](#behavior-animations)
* [Update animations](#update-animations)

### Timeline animations

The most important and necessary of the three types of animations is the timeline animation. Timeline animation defines what an overlay does when taken on and off air. Does an overlay fade, slide, or twirl when you take it on or off air?

### Behavior animations

Behavior animations allow you to add looping animations to Composer elements. This is useful for adding things like a flare or other living holds to an overlay. The purpose of behavior animations is to make overlays more alive while they are on-air. How do your overlays behave on air?

### Update animations

Update animations are triggered when new data is pushed to overlays. If an update animation is enabled, any new information sent to your overlay will update with an animation of your choosing. Think of a fade out and then a fade in when the score of your favorite sports team goes from 0 to 1 on the scoreboard.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developer.singular.live/singular-basics/building-overlays-in-composer/animating-overlays.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
