CSS Declaration Sorter

Travis Build Status npm version David Dependencies Status David devDependencies Status

A Node.js module and PostCSS plugin to sort CSS declarations based on their property names. Ensuring the CSS is organized, more consistent and in order... Besides, sorted CSS is smaller when gzipped because there will be more similar strings. The intention of this module is to sort the source CSS code of a project in the build process. Check out the Atom package for individual usage.

Alphabetical example

Input:

body {
    display: block;
    animation: none;
    color: #C55;
    border: 0;
}

Output:

body {
    animation: none;
    border: 0;
    color: #C55;
    display: block;
}

Niceness

  • Up-to-date CSS properties fetched from the MDN Web Platform.
  • Sort using your own defined order.
  • Nested rules sorting support.
  • Less and SCSS support when combined with either postcss-scss or postcss-less.
  • Thought-out sorting orders out of the box, approved by their authors.

Sorting orders

  • Alphabetically
    alphabetically
    Default, ordering in a simple alphabetical manner from a - z.

  • SMACSS
    smacss
    Ordering from most important, flow affecting properties, to least important properties.

    • Box
    • Border
    • Background
    • Text
    • Other
  • Concentric CSS
    concentric-css
    Starts outside the box model, moves inward.

    • Positioning
    • Visibility
    • Box model
    • Dimensions
    • Text
  • Custom order
    Provide your own order by passing the location of a JSON file containing an array.
