Question

When debugging HTML is there a way to listen for div width change using JavaScript or jQuery?
I have a div changing size due to some CSS and can’t figure out where, even stepping through.
I was wondering if there was a way to hook an event up to a div to see what is causing it to change?
Even if possible, I’m not sure how how would pass stack information for what caused the size change in the first place, so this may not even be possible.

This is bad way, but I’m not sure such event exists.

$(function(){
    var last = $("#your_div").width();
    setInterval(function(){
        if (last != $("#your_div").width()){
            alert('div width changed');
        }
    }, 100);
});
