should we include event,ui in the resize function every time we use resize so it looks like function(event, ui) instead of doing just function(). In what cases do we not include them in. And what exactly is ui.element. I can't find ui.element in the documentation.
$('div').live({
resize: function(event, ui){
var height = ui.element.height();
$('#wrapper_size').text(height);
}
