Description by publisher:

The year is 2014, and the internet and how we use it has evolved rapidly, most significantly in that we can access the web from anywhere, at any time, on-the-go, with mobile devices. Mobile First is a theme obsessed with mobile-first and responsive design. Whether at home on a traditional laptop/desktop or more importantly, out and about on your smartphone (iPhone, Android) or your tablet (iPad), the internet should adapt to you, not the other way around.
