Detect last item that is overlapped by class?

[grafxflow]

This is more help rather than a issue.

Is there a way to detect the last overlapping items class? on a window resize.

Something like

$(this).attr("class")

So if I have a line (top to bottom) of div's each with a number class at the end - so class="div1", class "div2" etc.

And there is the footer they overlap and I want to hide them.

Can I detect the class the last last current overlap by class?

Hope this makes sense.
