How do I find the offset of the bottom of my screen? Suppose I
sometimes display a DIV with a high z-index that overlays part of my
screen. And suppose sometimes part of this DIV is too low, and so
can't be seen. I want to scroll the main page lower, so that the
overlaying div can be seen in its entirety.
To do that, I need to know 2 numbers - the current y-position of
the bottom of the main page, and the current (hidden) y-position of
the bottom of the overlaying div.
What properties would I use and what objects would I use?
Thanks.
