Last week, Microsoft made its biggest announcement for the web since it first introduced Internet Explorer in 1995: a new browser, codenamed “Project Spartan.” So, what does this mean for us as designers and developers? What rendering engine will Spartan be using, and how will it affect our work? We spoke with Jacob Rossi, the senior engineer at Microsoft’s web platform team, about the new browser, the rendering engine behind it, and whether it’s going to replace Internet Explorer in the long run. This article, written by Jacob, is the result of our conversations, with a few insights that you may find quite useful. – Ed.
