New effects can be integrated with jQuery UI’s effects processing by extending $.effects.effect (or $.effects in versions of jQuery UI prior to 1.9). These effects are then available (identified by name) for use within the effect or enhanced show, hide, or toggle functions provided by jQuery UI. Each effect is a function that adds a callback function to the current element’s fx queue to implement its animation when earlier queued events have completed.

One of the most widely used of jQuery’s features is its animation functionality, which provides support for animating various properties of elements, resulting in visual changes on the web page. Besides the basic show and hide functions that provide an animated transition if a duration is specified, several slide and fade animations are also available as standard, such as slideDown and fadeIn. If you want something more exotic, you can request a custom animation to move an element to a particular position or to change its dimensions or font size by using the animate function.
