58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

VFIO Setup on NixOS

Disclaimer: Nobody else tested my setup so far, so this is a "works on my machine" scenario. I am not responsible for anything you break on your machine (although I'd not expect much harm).

Hardware

My system has the following hardware:

• Board: ASRock X570 Pro4

zjx20

• enable bbrplus on debian 9 and above

  git clone https://github.com/Xaster/bbrplus-debian.git
  cd bbrplus-debian
  # run as root
  make && make install
  
  sysctl -w net.core.default_qdisc=fq

sysctl -w net.ipv4.tcp_congestion_control=bbrplus
