1) Client's goals was frontend pages that he could use in backend side with Java Freemarker templates, as in frontend we don't have such template engine I suggested to use `Nunjucks` that was translated to html over `Gulp` (we used limited constructions that could be easy translated to Freemarker). As model in frontend we used external `json data`, that in backend should be changed to real data from database. 2) to make front I used `scss processor` for css styles, `Vue.Js` for client JS logic, as JS dependence manager - `bower`, build system - `npm/gulp` 3) for email layouting I choose `Foundation Email Framework` as standard for responsive layout for different email clients 4) in this project was wide used bootstrap popups, popovers and html5 dialog 5) all pages was made responsive for 3 desktop/tablet/phone screens. https://panser-portfolio.gitlab.io/numedeon-assignments/completionReport.html
