There is no UIKit for the Web
… because there are many. I am building a web application and … I need a UI Kit. I am tempted to start with a clean slate, an empty CSS file, but first I’ll look around. I feel weird because I never needed this scouting when I built iOS apps for clients. The starting point was always UIKit, like it or not. It has pros and cons, but it saves you from the situation I am in: choosing a framework (or starting from scratch).
