Interactive Buttons - Example
This page shows what can happen when two include pages containing Interactive Buttons are applied to a single page. If the whole page does not show, scroll down until the "Interactive Home" button on the left, and the "Button 3" button above the bottom border both show.
View the HTML (View Source) and notice that the left "Interactive Home" and bottom "Button 3" buttons both have the same id:
<img border="0" id="img1" src="../images/button4D.gif" .....>
<img border="0" id="img1" src="../images/button1A.gif" .....>
Mouse over this button, and the IB Home Page button in the left menu, and see the effect on the buttons. The effects vary with browsers - in IE9, for example, the "Button 3" button changes, in other browsers the "IB Home Page" button changes - and in some browsers both buttons change.
