Is there a screen resolution with a width of 340px?

Question

css

I think the essence of the question is clear, in the answer I want to see yes / no and yes, then write on which devices.
I know for sure there are 320, 360, 375, 384, 414, 424, 480 and 540

Answer 1

There is a database of devices indicating their viewport - judging by it, there is no such device.

Answer 2

Perhaps somewhere, someone has it
And what's the actual difference? Or do you specify a fixed block width for different screens? Use % and you will be happy
PS on average on the sites that I made up, it is enough to have 3 breakpoints, maximum 4

@mobile: ~"screen and (max-width: 768px)";
@mobile-portrait: ~"screen and (max-width: 480px)";
@mobile-landscape: ~"screen and (min-width: 481px) and (max-width: 768px)";
@tablet: ~"screen and (min-width: 769px) and (max-width: 1000px)";
@desktop: ~"screen and (min-width: 1001px)";
