postcss-color

PostCSS plugin to transform latest W3C CSS color module syntax to more compatible CSS.

This plugin can:

• transform color() to rgb() (or rgba()).
• transform RGBA hexadecimal notations (#RRGGBBAA or #RGBA) to rgba().
• transform hwb() to rgb() (or rgba()).
• transform rebeccapurple to rgb().

Installation

$ npm install postcss-color

Usage

// dependencies
var fs = require("fs")
var postcss = require("postcss")
var color = require("postcss-color")

// css to be processed
var css = fs.readFileSync("input.css", "utf8")

// process css
var output = postcss()
  .use(color())
  .process(css)
  .css

Using this input.css:

body {
  background:
    rgb(102, 51, 153)
    linear-gradient(
      color(rebeccapurple a(50%)),
      hwb(0, 20%, 40%),
      color(hwb(0, 20%, 40%, .5) a(+10%)),
      color(#9d9c a(90%))
    )
}

you will get:

body {
  background:
    rgb(102, 51, 153)
    linear-gradient(
      rgba(102, 51, 153, 0.5),
      rgb(153, 51, 51),
      rgba(153, 51, 51, 0.55),
      rgba(153, 221, 153, 0.9)
