I am experienced with handling this issue in flash, but I am struggling to figure out how to do it using Javascript and CSS. The problem involves an iframe that does not have an overflow property, and I need to modify its width/height. Is there a simple method to adjust these dimensions relative to a specific anchor point? Essentially, I have an advertisement that can be contracted or expanded. If the expansion moves leftward or upward, how can I adjust the width/height to ensure the entire ad is displayed?
