I am trying to set the width and height of a mask behind a modal window.
I am using $(document).width() and $(document).height().
Works great in FF and Chrome but IE adds about 25px to each and I end up with scroll bars? What am I supposed to use that is cross browser compatible?
I am using IE8 btw, but I want it to work down to 6 or 7.
Question: Are you using a doctype on your page? It sounds like the kind of glitch you may get if IE goes into quirks mode, which can be avoided if you use a doctype.
If you haven't got one, all you need is a very simple line at the top of your site:
<!DOCTYPE html>
Hope that helps.
If you are trying to fill up the view-port $(window).width() and $(window).height() is what you want to use. Works in IE.
