Transition similar to the native CSS, jQuery UI's animation class provides a smooth transition from one state to another state of transition, while ensuring that all the details of the style change is done via CSS without using JavaScript. All class animation, comprising .removeClass() , allows custom duration of the animation and easing function, the animation is complete also provides a callback.

Not all styles can be animated to add. For example, the background image animated. Not any animation style will change at the end of the animation.

The plug-ins extend the jQuery built .removeClass () method. If jQuery UI is not loaded, call .removeClass() method does not simply fail, because the method exists in jQuery. But it is not expected behavior.
