PostCSS pseudo shorthand

PostCSS plugin that expands pseudo aliases to browser specific aliases, to avoid writing the same CSS rules multiple times.

Example input

input[range]::range-thumb {
  background: green;
}

Example output

input[range]::-moz-range-thumb {
  background: green;
}
input[range]::-ms-thumb {
  background: green;
}
input[range]::-webkit-slider-thumb {
  background: green;
}

Usage

The example usage below has the default rules documented. More rules can be added without any majort version bump.

import postcssPseudoShorthand from 'postcss-pseudo-shorthand';

const config = {
  plugins: [
    postcssPseudoShortHand({
      rules: {
        '::color-swatch': ['::-moz-color-swatch', '::-webkit-color-swatch'],
        '::color-swatch-wrapper': ['::-moz-focus-inner', '::-webkit-color-swatch-wrapper'],
        '::range-thumb': ['::-moz-range-thumb', '::-ms-thumb', '::-webkit-slider-thumb'],
        '::range-track': ['::-moz-range-track', '::-ms-track', '::-webkit-slider-runnable-track'],
      },
    }),
  ],
};

export default config;
