document.getElementById("Id").style.top Not Working In Firefox
Hi,
I can for the life of me work out why this code works in IE and not Firefox. I am sure it is going to be something simple but I can not see the wood for the trees!
Summary: All this code does is put a message at the bottom of the browser based on the browsers active display area. I need to do this as height:100% no longer works with the new XHTML standards.
