postcss-combininator v1.1.0

postcss-combininator

Combines multiple blocks of custom properties

Installation

yarn add -D postcss-combininator

Usage

postcss -u postcss-combininator -o dist/index.css src/index.css

This plugin turns this:

.spectrum {
  --spectrum-actionbutton-background-color: blue;
  --spectrum-actionbutton-border-color: transparent;
}

.spectrum--express {
  --spectrum-actionbutton-background-color: purple;
}

Into this:

.spectrum--express {
  --spectrum-actionbutton-border-color: transparent;
  --spectrum-actionbutton-background-color: purple;
}

The resulting selector comes from the last rule, and all duplicate properties in the subsequent rules override the previous declarations.

Options

preserve

Type: 'auto' | 'first' | 'last' Default: 'auto'

By default ('auto'), the plugin removes all previous custom property definitions and preserves the last declaration. Other valid options include: 'first', 'last'.
