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;
}

require 'pathname'
require 'open3'
require 'mini_magick'

SRC_DIR = '/path/to/src/dir/'.freeze
TMP_DIR = '/path/to/tmp/dir/'.freeze

class TextReader
  def initialize(input_path, output_path)
    @input_path  = input_path

# Minimal example of getting a PostgREST API running from scratch for
# testing purposes.  It uses docker to launch a postgres database and
# a postgrest api server.

# This should not be used to deploy a production system but to
# understand how postgrest works.  In particular there is no security
# implemented, see the docs for more.

Docker Swarm Mode Ports

Starting with 1.12 in July 2016, Docker Swarm Mode is a built-in solution with built-in key/value store. Easier to get started, and fewer ports to configure.

Inbound Traffic for Swarm Management

• TCP port 2377 for cluster management & raft sync communications
• TCP and UDP port 7946 for "control plane" gossip discovery communication between all nodes
• UDP port 4789 for "data plane" VXLAN overlay network traffic
• IP Protocol 50 (ESP) if you plan on using overlay network with the encryption option
