PostCSS Calc 
PostCSS Calc lets you reduce calc() references whenever it's possible. This
can be particularly useful with the PostCSS Custom Properties plugin.
When multiple units are mixed together in the same expression, the calc()
statement is left as is, to fallback to the W3C calc() implementation.
Installation
1npm install postcss-calc
Usage
1// dependencies 2var fs = require("fs") 3var postcss = require("postcss") 4var calc = require("postcss-calc") 5 6// css to be processed 7var css = fs.readFileSync("input.css", "utf8") 8 9// process css 10var output = postcss() 11 .use(calc()) 12 .process(css) 13 .css
Example (with PostCSS Custom Properties enabled as well):
1// dependencies 2var fs = require("fs") 3var postcss = require("postcss") 4var customProperties = require("postcss-custom-properties") 5var calc = require("postcss-calc") 6 7// css to be processed 8var css = fs.readFileSync("input.css", "utf8") 9 10// process css 11var output = postcss() 12 .use(customProperties()) 13 .use(calc()) 14 .process(css) 15 .css
Using this input.css:
1:root { 2 --main-font-size: 16px; 3} 4 5body { 6 font-size: var(--main-font-size); 7} 8 9h1 { 10 font-size: calc(var(--main-font-size) * 2); 11 height: calc(100px - 2em); 12 margin-bottom: calc( 13 var(--main-font-size) 14 * 1.5 15 ) 16}
you will get:
1body { 2 font-size: 16px 3} 4 5h1 { 6 font-size: 32px; 7 height: calc(100px - 2em); 8 margin-bottom: 24px 9}
Checkout tests for more examples.

1var out = postcss() 2 .use(calc({preserve: true})) 3 .process(css) 4 .css

1var out = postcss() 2 .use(calc({mediaQueries: true})) 3 .process(css) 4 .css
selectors (default: false)
Allows calc() usage as part of selectors.
1var out = postcss() 2 .use(calc({selectors: true})) 3 .process(css) 4 .css
