PostCSS Exponential Functions

npm install @csstools/postcss-exponential-functions --save-dev

PostCSS Exponential Functions lets you use the pow(), sqrt(), hypot(), log(), exp() functions following the CSS Values 4 Specification.

.foo {
    top: calc(1px * pow(2, 3));
    line-height: sqrt(1.2);
    padding: hypot(3px, 4px);
    order: log(10, 10);
    min-height: calc(e - exp(1));
}

/* becomes */

.foo {
    top: calc(8px);
    line-height: calc(1.09545);
    padding: calc(5px);
    order: calc(1);
    min-height: calc(0);
}

Usage

Add PostCSS Exponential Functions to your project:

npm install postcss @csstools/postcss-exponential-functions --save-dev

Use it as a PostCSS plugin:

const postcss = require('postcss');
const postcssExponentialFunctions = require('@csstools/postcss-exponential-functions');

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

Options

preserve

The preserve option determines whether the original notation is preserved. By default, it is not preserved.

postcssExponentialFunctions({ preserve: true })

.foo {
    top: calc(1px * pow(2, 3));
    line-height: sqrt(1.2);
    padding: hypot(3px, 4px);
    order: log(10, 10);
    min-height: calc(e - exp(1));
}

/* becomes */

.foo {
    top: calc(8px);
    top: calc(1px * pow(2, 3));
    line-height: calc(1.09545);
    line-height: sqrt(1.2);
    padding: calc(5px);
    padding: hypot(3px, 4px);
    order: calc(1);
    order: log(10, 10);
    min-height: calc(0);
    min-height: calc(e - exp(1));
}
