Definition and Usage

The animate() method performs a custom animation of a set of CSS properties.

This method changes an element from one state to another with CSS styles. The CSS property value is changed gradually, to create an animated effect.

Only numeric values can be animated (like "margin:30px"). String values cannot be animated (like "background-color:red").

Tip: Use "+=" or "-=" for relative animations.

Syntax

(selector).animate({styles},speed,easing,callback)

Parameter Description
styles Required. Specifies one or more CSS properties/values to animate

Note: The property names must be camel-cased when used with the animate() method: You will need to write paddingLeft instead of padding-left, marginRight instead of margin-right, and so on

Properties that can be animated:

Tip: Color animations are not included in the core jQuery library. If you want to animate color, you need to download the Color Animations plugin from jQuery.com
speed Optional. Specifies the speed of the animation

Possible values:

  • milliseconds
  • "slow"
  • "fast"

  • "linear" - moves in a constant speed
Tip: More easing functions are available in external plugins
callback Optional. A function to be executed after the animation completes
