Creating designs which are as effective and pleasing to the eye on a desktop PC as they are on a mobile device presents any designer with a number of challenges. The reality is that creating responsive websites for mobile devices is a skill every single web designer needs to learn, unless they want to be left behind when the industry, and its customers, moves forwards. One of the key areas to focus on when looking at the typography for a mobile site is a better understanding of
audience behaviour and need; if you can gain a better understanding of that then your mobile web
typography will improve dramatically as a result.
