The description box that pops up when you click on a map object (area, image, or just about anything else) that has a "description" property is basically a <div> element that can be customized like any HTML element.
To do that use the following CSS classes:
| CSS Class | Applies to |
| ammapDescriptionWindow | The whole description box window (outer container). You might want to set background / borders in this class. |
| ammapDescriptionWindowCloseButton | Close button. You can use it to reposition, change color or even override the image itself here. |
| ammapDescriptionTitle | The title that appears at the top of the description box. By default it contains the title of the clicked object. |
| ammapDescriptionText | Body of the description box. That's where everything from "description" property goes into. |
As for the contents of the description box, it can contain any valid HTML including CSS-styled elements.
