In this video tutorial I walk through some of the different ways to theme an Ionic 2 application. There was no particular plan for the video, I just wanted to jump in and show you some of the steps I would usually take when theming an application, and the methods I prefer to use. Rather than being about the high level theory, this video should hopefully show a realistic scenario of hacking away at an application.
