In my favorite stories and films, there's usually a scene where a mentor passes on valuable advice and some magical items to the hero. You know those items will prove useful; you just don't know when or how.
Well, I'd like to assume the role of the mentor in this final chapter (plus my hair has waned, and I don't have the looks for the hero role). I would like you, my fine apprentice, to spare me just a few more moments of your time while I offer up some final words of advice before you set forth on your responsive quest.
This chapter will be half philosophical musings and guidance, and half grab-bag of unrelated tips and techniques. I hope at some point in your responsive adventures, these tips will prove useful. Here's what we'll cover:
Getting designs in the browser and on real devices as soon as possible
Letting the design dictate the breakpoints
Embracing progressive enhancement
Defining a browser support matrix
Progressive enhancement in practice...
