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;
}

-- LFSRs are good for games where you want a random number generator with a short period,
-- so that speed runners can device tactics to control the RNG's state.
-- Otherwise they're a bit of an obsolete piece of tech.
-- See: https://en.wikipedia.org/wiki/Linear-feedback_shift_register

-- LFSRs work by shifting all of the bits to the right by one, and using the shifted
-- out bit to XOR in at specific taps. Another way to put it is that they first check
-- if the state is odd, then divides by two, and if it was odd, Exclusive-Ors in a value.
-- The bit shifted out is suitably random. Want more bits, cycle the generator more.
