    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;
}

    If you want to learn Scala, I’d suggest:


  Install IntelliJ + Scala Plugin
  Don’t do the Coursera courses yet.
  Don’t do the “red book”  Functional Programming in Scala yet.
  Do: http://underscore.io/books/
    
      Essential Scala
      Essential Play
      Essential Slick
    
  
  Do Scala for the Impatient: https://www.amazon.com/Scala-Impatient-Cay-S-Horstmann/dp/0321774094

Trello CSS Guide

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”
You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?
