Enable PostCSS plugins directly in your stylesheet.

@use postcss-preset-env(stage: 0, browsers: "last 2 versions");
h1 {
  & a {
    color: red
  }
}

With npm do:

npm install postcss-use --save

Options may be passed into plugins as a JSON object, an array, a hash map, or as declarations. Hash maps will follow the format of option: value, option2: value2.

With postcss-discard-comments:

@use postcss-discard-comments(removeAll: true);
/*! test */
h1 {
    color: red
}

You may also use configuration blocks that are more CSS-like. Note that root array options cannot be parsed by this method.

@use postcss-discard-comments {
    removeAll: true
}

h1 {
    color: red
}

Type: array|string Required option.

The modules option specifies a list of allowable PostCSS Plugins, expressed as a String, Array, or RegExp. By default, all plugins are disabled in order to prevent malicious usage in browser environments.

use({
  // allow plugins starting with autoprefixer, postcss, precss, and cssnano
  modules: [
    /^autoprefixer/,
    /^postcss/,
    /^precss/,
    /^cssnano/
  ]
})

use({
  // allow autoprefixer, postcss-preset-env, and postcss-flexbugs-fixes
  modules: [ 'autoprefixer', 'postcss-preset-env', 'postcss-flexbugs-fixes' ]
})

Setting the option to "*" will allow PostCSS Use to require any plugins. This is not recommended for environments where you may be accepting arbitrary user input; use at your own risk.

Type: boolean (default: false)

The resolveFromFile option specifies whether plugins should be resolved relative to the file that referenced them. This may be used to enable the usage of different versions of the same plugin. By default, it is disabled.

use({
  resolveFromFile: true
})

Type: object (default: {})

The options option specifies individual options for specific plugins by plugin name.

use({
  options: {
    'postcss-preset-env': {
      stage: 0,
      browsers: 'last two versions'
    }
  }
})

See the PostCSS documentation for examples for your environment.
