I'm not sure how you feel, but I consider myself a backend developer. Sure - I know my way around Vue.JS and really enjoy working with it, but writing CSS has never been my strong point. At one of our companies recent projects, we are working together with another development team, which is mostly taking care of frontend development. So we build controllers, repositories, services, etc. and hand it over to some basic views. They handle the rest. We introduced continuous integration to them and showed them our usual workflow, when I thought that it would be excellent to also have some kind of visual CI for frontend changes.
