postcss-generate-preset

PostCSS plugin that allows quick generation of rules. Useful for quickly creating repetitive utilities.

Installation

$ npm install postcss-generate-preset

Usage

input.css

@generate-preset .u-mp margin padding 0 10px;
@generate-preset .u-mt margin-top 10px 20px;

output.css

.u-mp0 {
  margin: 0;
  padding: 0;
}

.u-mp10 {
  margin: 10px;
  padding: 10px;
}

.u-mt10 {
  margin-top: 10px;
}

.u-mt20 {
  margin-top: 20px;
}

var presets = require('postcss-generate-preset');
postcss([ presets() ])

Options

useImportant (default: false)

When set to true all declarations will use !important. Often useful when utility classes need to override component styles

zeroValue (default): false)

The default is to add zero to a selector. In some cases it might be desirable to display it differently

presets({ zeroValue: 'Z' });

@generate-preset .u-m margin 0;

/* becomes */

.u-mZ {
  margin: 0;
}
