// Prereq: underscore.js and jquery loaded

var p1 = $.Deferred();
var p2 = $.Deferred();

// We want something that chains promises, so something like...
//p1.done(

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;
}
