58 bytes of css to look great nearly everywhere

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;
}

Let's fix `class` in ES7

Two Simple Changes to Simplify class

I'm not suggesting drastic action. I don't want to break backwards compatibility. I simply want to make the class feature more usable to a broader cross section of the community. I believe there is some low-hanging fruit that can be harvested to that end.

Imagine AutoMaker contained class Car, but the author wants to take advantage of prototypes to enable factory polymorphism in order to dynamically swap out implementation.

Stampit does something similar to this in order to supply information needed to inherit from composable factory functions, known as stamps.

This isn't the only way to achieve this, but it is a convenient way which is compatible with .call(), .apply(), and .bind().

ESLint Reset - A starter .eslintrc file that resets all rules to off and includes a description of what each rule does. From here, enable the rules that you care about by changing the 0 to a 1 or 2. 1 means warning (will not affect exit code) and 2 means error (will affect exit code).
{
// http://eslint.org/docs/rules/
"ecmaFeatures": {
"binaryLiterals": false, // enable binary literals

"defaultParams": false, // enable default function parameters
"forOf": false, // enable for-of loops
"generators": false, // enable generators
