If it makes you feel any better, I must disagree with brundolf here and confirm that figuring out "which of these 1,500 DOM elements is the reason that between 321 to 334px width one of my container divs simply refuses to stay within screen boundaries" can be absolutely maddening and I have no idea how one would ease that process. Element sizing in CSS is anything but straight forward, especially as there are loads of non obvious rules applied to elements like text inputs etc But maybe I am just not as good at CSS as I thought :)
