I\'m working on a fluid layout project. I have some fixed height DIVs in my document, and the heights are different for all of them. I need to proportionally change these DI
use .data to store the initial size of the div inside your $.each function
$(this).data('height', $(this).height());
$(this).data('width', $(this).width());
you can later retrieve the old sizes within the resize callback
var old_height = $(this).data('height');
var old_width = $(this).data('width');
Hope this helps
