# jQuery.fx.interval

## jQuery.fx.interval ( ) Returns: Number version added: 1.4.3

Description: The rate (in milliseconds) at which animations fire.

This property can be manipulated to adjust the number of frames per second at which animations will run. The default is 13 milliseconds. Making this a lower number could make the animations run smoother in faster browsers (such as Chrome) but there may be performance and CPU implications of doing so.

Since jQuery uses one global interval, no animation should be running or all animations should stop for the change of this property to take effect.

## Examples:

#### Example: Cause all animations to run with less frames.

    <html lang="en">

      div {
        width: 50px;
        height: 30px;
        margin: 5px;
        float: left;
        background: green;
      }
