On: How to detect DOM changes in CSS

[jQueryIsAwesome]

I would like to mention that when you working over a stable JS DOM manipulation framework you can intercept events and easily create your custom mutation detection solution; fast and cross-browser.

A little example using jQuery:

    _append = $.fn.append
    $.fn.append = function(){
        $(this).trigger("mutated");
        return _append.apply(this,arguments)
    }
