postcss-remove-null

Remove null values with PostCSS.

Functionality

The basic use case of this plugin functions very similar to null in Sass.

Given

div {
  display: null;
}

The plugin will output

div {}

It's recommended that this plugin be followed by cssnano or postcss-discard-empty to ensure that the div in the above example is removed.

This plugin also intelligently handles nulls present in shorthand declarations.

Given

div {
  margin: null 1px null 2px;
}

The plugin will output

div {
  margin-right: 1px;
  margin-left: 2px;
}

Usage

var postcss    = require('postcss');
var removeNull = require('postcss-remove-null');
var cssNano    = require('cssnano');
