Here is the basic logic for generating the HTML: function BuildTable( data ) { var div = document.getElementById(...
I am trying to implement a simple fold/unforld effect for elastic div's, i.e. when actual dimensions of an element are not set through CSS and thus are not trivially determinable. So I need equivalents of jQuery's width() and height() for arbitrary elements; the methods should return something that would be assignable to *.style.width/he...
