Is it impossible for websites to use my horizontal space? I don't like having a tiny bar in the middle when I have 300 unused pixels either side of the text, this phone centric internet is really annoying on desktop.
Make it too long and you may have trouble to find the next line. Make it too short and your eyes will suffer from traveling back too often.
When I come upon a site that uses too much horizontal space for me to read comfortably, I just leave.
