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;
}

CREATE ROLE new_user WITH PASSWORD 'somepassword';
-- 2. Grant the required permissions. This grants select, insert, update, and delete on all tables in the public schema.
-- I also gave execute to all functions in the public schema as well.
