# postcss-calc [![Build Status](https://travis-ci.org/postcss/postcss-calc.png)](https://travis-ci.org/postcss/postcss-calc)

A [PostCSS](https://github.com/postcss/postcss) plugin to reduce `calc()` usage.

> [PostCSS](https://github.com/postcss/postcss) plugin to reduce `calc()`.

Particularly useful with the [postcss-custom-properties](https://github.com/postcss/postcss-custom-properties)

This reduce `calc()` references whenever it's possible.

This can be particularly useful with the [postcss-custom-properties](https://github.com/postcss/postcss-custom-properties) plugin.

**Note:** When multiple units are mixed together in the same expression, the `calc()` statement is left as is, to fallback to the [w3c calc() feature](http://www.w3.org/TR/css3-values/#calc).

**Example** (with [postcss-custom-properties](https://github.com/postcss/postcss-custom-properties) enabled as well):

var customProperties = require("postcss-custom-properties")

var css = fs.readFileSync("style.css", "utf8")

  font-size: calc(var(--main-font-size) * 2);

See [unit tests](test) for a better example.
