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;
}

These are some notes from reading Ian Lance Taylor's 20-part essay on linkers. Prettified version on gist.io.

I'm not going to describe the basics of what a linker does because I know already. I talk a little about linkers in How to call Rust from assembly, and I found this Beginner's guide to linkers pretty helpful. Parts [1] and [2] of the essay also discuss "what's a linker?".
