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;
}

/***** "Remote" server first *****/
-- Note: Unless the object you are trying to gain access to is in the same DATABASE, it's a remote datebase. Even if it's
-- on the same node!
-- 1. create the role and assign it a password. Note: CREATE USER is an alias for CREATE ROLE. Either one is fine
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.
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO new_user;
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA public TO new_user;
