Here is a button I created. There is a thick border around the image to help define it.
Designers like to use graphical buttons for navigation.
Each button is almost like the next, except for the text on the button. This means that for ten items, ten separate buttons must be downloaded. The difference in each button is minor, and yet ten different images must be used and thus ten different downloads must be occur. Let's see if we can find a way to use one button image over and over again for each navigation element. We'll use HTML to generate the text for each navigation button.
