It’s utterly impossible to truly make something that will resize to fit ANY viewport—it’s just not financially nor time feasible.

Code your sites using standards and make it work at any breakpoint. There’s a 99.9999999999999999% chance that if it works on iOS and at least one Android device—it’ll work on everything else. Stop optimizing for specific devices and stop making things more complicated than they have to be.
