The problem is that nobody really does "mobile-first". ~everybody designs/builds on desktop, and few know about or use chrome://inspect as they core of their workflow: https://developers.google.com/web/tools/chrome-devtools/remote-debugging …https://twitter.com/adactio/status/1180144204871327744 …
Explicitly added the "~" to account for the rounding error fraction of folks who are doing it right. Most build in & for desktop context and fail to do mobile-first. They aren't doing RWD as you and I understand it, but they call it that. The words were stripped of intent.
