  $( "#box" ).animate({
   width: "300px",
   height: "300px", 
    }, 1500 );
});

In jQuery animate( properties [, duration ] [, easing ] [, complete ] ) method is used to perform a custom animation of a set of CSS properties. It has the following parameters :

  • properties : An object of CSS properties and values that the animation will move toward. [Type- PlainObject]
  • duration : A string or number determining how long the animation will run. [Type- Number or String]

  • complete : A function to call once the animation is complete. [Type: Function()]

The only required parameter is a plain object of CSS properties.
