I have a simple test page with a div where the left and right margins
are set to auto. The div has a width and when viewed it's centered on
the page. When I try to read the left or right margin with jQuery it's
returned as "0px" instead of auto. I'm trying to add a div to a page
and set the new div's margin to match an existing div's margin, but
without being able to read "auto", it's failing. My tests using alert($
('#container').css('margin-left')); and alert($('#container').css
('marginLeft')); yielded the same results.
