.example-1 {
	background: linear-gradient(red 50%, blue ++1px);
}

.example-2 {
	background: conic-gradient(red ++60deg, blue ++10deg ++50deg, green ++60deg, yellow ++60deg);
}

.example-3 {
	background: conic-gradient(pink ++60deg, cyan 0 ++20deg, gold 0 ++10deg);
}

.example-4 {
	background: linear-gradient(orange 20px, magenta 2vi, aqua ++2vw);
}

/* becomes */

.example-1 {
	background: linear-gradient(red 50%, blue calc(50% + +1px));
}

.example-2 {
	background: conic-gradient(red +60deg, blue 70deg 120deg, green 180deg, yellow 240deg);
}

.example-3 {
	background: conic-gradient(pink +60deg, cyan 0 80deg, gold 0 90deg);
}

.example-4 {
	background: linear-gradient(orange 20px, magenta 2vi, aqua calc(max(20px, 2vi) + +2vw));
}

Usage

Add PostCSS Gradient Stop Increments to your project:

npm install postcss @csstools/postcss-gradient-stop-increments-experimental --save-dev

Use it as a PostCSS plugin:

const postcss = require('postcss');
const postcssGradientStopIncrementsExperimental = require('@csstools/postcss-gradient-stop-increments-experimental');

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

Options

preserve

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

postcssGradientStopIncrementsExperimental({ preserve: true })
