Mike comments on this video: "I think this is one of my best tutorials to date. I show you how to accomplish the goal assuming that you know nothing about it. I even left in my mistakes and thought process so you could learn how I would approach the problem from beginning to end. Anyone new to responsive design or working with this skin is going to find this reference invaluable."
