If you’re building an enterprise type of dashboard app, mainly used in an office/desktop setting. I would design for desktop > tablet. And not even bother with mobile phones. Then you can always develop a dedicated mobile app, and be cheeky enough to charge more for it (e.g. higher tier plans get access to mobile app).
If you’re building a more everyday type of app, e.g. a sneaker listing app or what have you. I would go Mobile > Tablet > Desktop. Especially if your target audience are younger, a lot of youngsters today access internet on their pocket machines, some doesn’t even have desktop/laptops. * gasp *
My app would be mostly for distance education and targets 6-20, so I guess mobile first then to desktop.
I want to ask if you design it from 360px how do you scale it up since when I use responsive mode from 360 px to like 1200px the groups and elements would not move and it would just widen the width. I would also not be able to move around the groups since my size is limited to only 360 px.
The responsive engine is a beast on its own. I spent hours watching videos and doing trial and error before I was able to make sense of it. It’s hard to wrap up in a forum post how it works and all the quirks. The best suggestion I can give is, watch videos and do trial and error, unfortunately.
For the specific case you mention, have a look at wrap to previous line.
