PostCSS Nested Calc

PostCSS Nested Calc lets you use nested calc() expressions following the CSS Values and Units 4 specification.

.example {
    order: calc(1 + calc(2 * 2));
}

/* becomes */

.example {
    order: calc(1 + (2 * 2));
    order: calc(1 + calc(2 * 2));
}

Usage

Add PostCSS Nested Calc to your project:

npm install postcss @csstools/postcss-nested-calc --save-dev

Use it as a PostCSS plugin:

const postcss = require('postcss');
const postcssNestedCalc = require('@csstools/postcss-nested-calc');

postcss([
    postcssNestedCalc(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);

PostCSS Nested Calc runs in all Node environments, with special instructions for:

Node	PostCSS CLI	Webpack	Create React App	Gulp	Grunt

Options

preserve

The preserve option determines whether the original notation is preserved. By default the original values are preserved.

postcssNestedCalc({ preserve: false })

.example {
    order: calc(1 + calc(2 * 2));
}

/* becomes */

.example {
    order: calc(1 + (2 * 2));
}
