The language of the Web is HTML, and it has its limitations with regards to links. The effect of a button is to change the mouse pointer when you rollover it, thus indicating to the user that it is a button. However, with the addition of the Javascript language you can create a rollover state. This means that the graphic used to display the button can be swapped when the mouse is on top of it, giving you the opportunity to create a more interesting result. It is possible to create more complicated buttons than this, using Macromedia Flash and we will talk about this later. First we should animate our button in our 3D program in order to create our rollover states.
