Scaling
Resources should scale to fill available space gracefully when a browser is resized. Techniques for graceful scaling include using relative rather than absolute size definitions within XHTML and use of scalable vector graphics within Flash objects.
When a standalone object does not have the ability to scale, the recommended fixed size of the object is 760 x 570 pixels. The fixed size of the learning object may be smaller but no larger than 760 x 570 pixels.
