My Photoshop Classroom

This is the story of what we learned during a redesign for our most demanding client — ourselves! In this article, I will explain, from our own experience of refreshing our agency website, why we abandoned a separate mobile website and will review our process of creating a new responsive design.
At Cyber-Duck, we have been designing both responsive websites and adaptive mobile websites for several years now. Both options, of course, have their pros and cons. With a separate mobile website, you have the opportunity to tailor content and even interactions to the context of your users, whereas a responsive website means better content parity for users and a single website to maintain.
