Minor comment regarding CSS: Flexbox alone was never supposed to fix layout; the real magic is supposed to be Flexbox + CSS Grid. As I understand it, Flexbox is truly designed for use in one dimension to govern local dynamic behavior within a larger CSS Grid layout that structures the whole page. At the moment the problem is the lack of CSS Grid adoption by browsers (see http://caniuse.com/#feat=css-grid). I'm still hopeful that the state of CSS layouts will drastically improve once Grid and Flexbox are both sufficiently supported.
