Does it make sense to separate mobile and desktop CSS in two separate files when serving the site over http/2?
As I understand, that way you can omit loading desktop styles on mobile, thus achieving faster loading times. With http/1.1 it would require an additional resource request though, so you would concatenate it in the one file.
But with http/2 it should load in parallel I suppose. Are there any downsides to the approach?
