  multiple: 2,
  units: ['vw'],

}
.custom .design-a {
  width: 8.21vw;

Usage

//postcss.config.js
module.exports = {
  plugins:[
    require('postcss-design-convert')({
      multiple: 2,
      units: ['vw'],
      selector: /\.design-/
    })
  ]
}

//.postcssrc.js
module.exports = {
  'plugins': {
    'postcss-design-convert' : {
      multiple: 2,
      units: ['vw'],
      selector: /\.design-/
    }
  }
}

Options

1. multiple (number) default 2: how many times the design draft needs to be multiplied

2. units (array<string>) default ['vw']: the units to be converted

3. selector (string | Reg) default /./: used to filter out the style to be converted (version compatibility reasons, alias [classRule])

4. attribute (string | Reg): used to filter out the attributes to be converted
