I have a page that uses an iframe to display real time information. The iframe resizes according to
content. However, although the page grows to accommodate the iframe content, the body does not shrink back when the iframe is reduced in size. Instead, the page will display a blank space below the frame. How can I shrink the size of the body back to it's original size, that is to say, assure that the space below the iframe is also resized accordingly. At present, it grows as needed but does not shrink if the content in the iframe becomes shorter. How do I ascertain the current length of the page and reset the body size?
