Package Exports

precsss
precsss/index.js
precsss/index.mjs

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (precsss) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

!!! This project is a replica of PreCSSS, because PreCSSS is no longer maintained !!!.

PreCSSS

PreCSSS lets you use Sass-like markup and staged CSS features in CSS.

$blue: #056ef0;
$column: 200px;

.menu {
  width: calc(4 * $column);
}

.menu_link {
  background: $blue;
  width: $column;
}

/* becomes */

.menu {
  width: calc(4 * 200px);
}

.menu_link {
  background: #056ef0;
  width: 200px;
}

PreCSSS combines Sass-like syntactical sugar — like variables, conditionals, and iterators — with emerging CSS features — like logical and custom properties, media query ranges, and image sets.
