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;
}

/* This mixin is for generating CSS arrows on a box */
@mixin box-arrow($arrowDirection, $arrowColor, $arrowSize: 10px) {
  position: relative;
  z-index: 10;

  &::after {
    content: '';
    width: 0;
    height: 0;

About

These functions use one or two 'base' colors to automatically generate a color range similar to Material Design's color ranges. Useful to quickly get different shades of your primary brand color or accent color, or to generate a set of neutrals between hand-selected light and dark colors.

Usage

$greens: make-shades(#cc99cc);
// (
//   100: #eeddee,
// 200: #ddbbdd,

Pure SASS-adaption of Lea Verou's contrast-ratio javascript. Can be useful when eg. generating colored buttons from a single supplied color as you can then check which out of a couple of text colors would give the best contrast.

This script currently lacks the support for alpha-transparency that Lea supports in her script though.

In addition to the color-contrast adaption there's also some math methods that were needed to be able to calculate the exponent of a number and especially so when the exponent is a decimal number. A 2.4 exponent is used to calculate the luminance of a color and calculating such a thing is not something that SASS supports out of the box and not something I found a good pure-SASS script for calculating and I much prefer pure-SASS over ruby extensions. The math methods might perhaps be unecessary though if you're running Compass or similar as they may provide compatible math methods themselves.

Normal usage: `color: pick_best_color(#f00
