Chapter 13. Dynamic Techniques: The Basics > Changing an Object's Visible Area

Changing an Object's Visible Area

The clipping region of an object defines how much of that object is visible in the window (see "Setting the Visible Area of an Element" in Chapter 9). If it is left alone, the entire object is visible. But if you clip the object, you can have as much or as little of it visible as you want, and you can use JavaScript to determine the clipping region (see "Finding an Object's Visible Area" in Chapter 12). In addition, DHTML allows you to change the clipping region on the fly (Code 13.6 and Figures 13.9 and 13.10).
