The animate method

All custom animations with jQuery are driven with the animate() method. Despite the ability to animate almost any style property that has a numeric value, the method is simple to use and takes just a few arguments. The method may be used in the following way:

jQuery(elements).animate(properties to animate,
  [duration],
  [easing],
  [callback]
);

The first argument should take the form of an object where each property of the object is a style that we'd like to animate, very similar to how we would use jQuery's css() method.

As I mentioned before, this can be any CSS style that takes a purely numerical argument (with the exception of colors, although with the jQuery UI library we can animate colors as well. See Chapter 6, Extended Animations with jQuery UI for more information on jQuery UI). Background positions cannot be animated by jQuery natively, but it is quite easy to animate this property manually; see Chapter 7, Full Page Animations for more information on this technique...
