A research project was the last module of a masters course in Mobile Web Development, completed at the end of December 2015. Below you can see a selection of screenshots from the practical side of the research project. Through the use of a basic prototype side I looked at the usability of current responsive web frameworks Bootstrap, Foundation, and Skeleton. In the end Bootstrap was focused on more thoroughly and evaluated both on its usability through the use of a system usability scale questionnaire and its cross-browser compatibility across desktop, tablet, and mobile devices.
