## jQuery.fx.off Returns: Boolean

Description: Globally disable all animations.

- #### version added: 1.3jQuery.fx.off

When this property is set to `true`, all animation methods will immediately set elements to their final state when called, rather than displaying an effect. This may be desirable for a couple reasons:

- jQuery is being used on a low-resource device.
- Users are encountering accessibility problems with the animations.

Animations can be turned back on by setting the property to `false`.

## Example:

Toggle animation on and off
