How many times you met that situation when you need to use a javascript code for getting a size of a specific part of the window or document or object from window? What can I say about the differences between browsers? This is far away from reality? Well ... not really. From here you can take some snippets of code for using in your web page as need it. This may work on other browsers and lower version of Intenet Explorer but we did not test them.
