CSS Sticky Footers with Unknown Height

Question

Is there any way to stick a footer to the bottom of the browser screen or right after the content (depending on which is longer) using CSS without knowing the size

Answer 1

since no one knows the answer for sticky footer w/o knowing the height of it, using css (crosbrowser solution), i was forced to calculate it

jquery:

if( $(document).height() < $(window).height() )
{
    $('#content').height
    (
        $(window).height - $('#footer').height()
    );
}

html structure:
