# PreCSS [
][postcss]
[![NPM Version][npm-img]][npm-url]
[![Build Status][cli-img]][cli-url]
[![Support Chat][git-img]][git-url]
[PreCSS] lets you use Sass-like markup and staged CSS features in CSS.
```scss
$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;
}
```
PreCSS 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.
