I know that one technique is to include some css files on main one with @import. Isn't this a bad practice? Because with @import browser still makes the request, and if the main is blank then you could endup with n+1 requests.
Could not get you. Do you mean other ways of doing apart from import would mean it will not do the request?
It was a question... I just said (but i'm waiting for someone to tell me is i'm right): when you have three css files and use anoter one to import all of them, this will endup with 4 requests (main plus other three) or is just the main (1 request)
