        /*Is it possible to manipulate ALL CSS properties with the animate() method?

        Yes, almost! However, there is one important thing to remember: all 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.

        Also, color animation is not included in the core jQuery library.
        If you want to animate color, you need to download the Color Animations plugin from jQuery.com.*/
