PostCSS Short <img src="https://postcss.github.io/postcss/logo.svg" alt="PostCSS" width="90" height="90" align="right">

PostCSS Short lets you use advanced shorthand properties in CSS.

PostCSS Short has been featured in Smashing Magazine. I hope all of these shorthands are useful and clear to first-time lookers. I hope they improve the readability of your stylesheets and save you development time along the way. Thank you so much for your support.

Options

features

Each plugin’s options may be configured by targeting the plugin’s namespace. Any plugin may be disabled by setting the plugin’s options as false.

postcssShort({
  features: {
    'font-size': {
      prefix: 'x'
    },
    'position': false
  }
});

prefix

The prefix option defines a prefix required by properties being transformed. Wrapping dashes are automatically applied, so that x would transform -x-border.

postcssShort({ prefix: 'x' });

.example-1 {
  -x-border-color: blue blue *;
  -x-color: * #fafafa;
}

/* becomes */

.example-1 {
  border-top-color: blue;
  border-right-color: blue;
  border-left-color: blue;
  background-color: #fafafa;
}

skip

The skip option defines the skip token used to ignore portions of the shorthand.

postcssShort({ skip: '-' });

.example-1 {
  border-color: blue blue -;
  color: - #fafafa;
}

/* becomes */

.example-1 {
  border-top-color: blue;
  border-right-color: blue;
  border-left-color: blue;
  background-color: #fafafa;
}
