Accoutrement 3.0.1

Sass Accoutrement

Build Status

Robust design systems require meaningful, readable, reusable code. These Sass utilities are designed to help define and manage your design tokens (colors, fonts, sizes, etc.) in a format that can be understood by both humans and parsers – opening the door for automation, while improving consistency and readability. These tools also integrate with Herman, our automated living pattern-library generator built on SassDoc.

Brought to you by OddBird – the creators of Susy, True, and Herman.


Install the package with npm or yarn

npm install accoutrement [--save-dev]
yarn add accoutrement [--dev]

Import what you need:

// core and all plugins (also available with `/index`)
@import "<path-to>/accoutrement/sass/tools";

// init normalization
@import "<path-to>/accoutrement/sass/init";

// individual plugins (core is required)
@import "<path-to>/accoutrement/sass/core";
@import "<path-to>/accoutrement/sass/plugin/<name>";

If you’re using Eyeglass, you can import the default “tools” (core + plugins) using only:

@import "accoutrement";


The accoutrement tools are built around a shared data-storage syntax using Sass “map” objects:

$map: (
  "root": 16px,
  "gutter": 1em,

Using a custom syntax, we can extend maps to handle internal reference, and functional adjustments – capturing meaningful relationships between design tokens:

$map: (
  "root": 16px,
  // internal reference & adjustments
  "gutter": "#root"
      "_major-third": 1,
      "convert-units": "rem",

Map storage serves a larger purpose:

  • Related data is grouped explicitly, making the code more readable and maintainable
  • The “single source of truth” encourages reusable design patterns
  • Meaningful structure allows automation, from automated style guides to automated functionality (provided in the plugins)


The Core module provides the generic (non data-specific) setup and syntax parsing:


We provide light-weight browser-normalization, as a distinct include. This is not part of the accoutrement/sass/tools package because it is the only module to produce direct CSS output.


While the core module handles generic data-management, we also provide plugins for a few common data types:

  • Animate – Tools for managing CSS transitions and animations
  • Color – Tools for managing CSS colors and contrast-ratios
  • Scale – Tools for managing CSS sizes: typographic scales, spacing, etc.
  • Type – Tools for managing webfonts, generated content, and other text needs
