I have spent the last 12 months researching and developing responsive websites using WordPress based on my own responsive WordPress themes. During that time, there has been an explosion in smartphone and tablet adoption and huge usage growth for mobile web traffic. The trouble is that the majority of websites, particularly websites developed in Australia, are not optimised or designed to meet the demands of the ever-increasing mobile web audience. This is why I have spent the latter half of this year studying mobile-first development, and applying what I know through developing responsive, mobile-first WordPress themes. I’d like to share my experience and findings with the Australian WordPress community in hope that we can design and develop better websites for the ever-increasing mobile market.
