Skeleton Sass 3

Skeleton Sass is a highly modular version of Skeleton CSS.

Key Features

  • Ability to seamlessly adjust grids by changing the value of variables
  • Themes
  • Easy-to-use mixins and functions
  • Install Skeleton Sass with bower or npm! No more clunky scripts!
  • Live demo!
  • Heavily documented


Does this work with other Sass compilers?

Yes! Skeleton Sass 3 has been tested with the following compilers and libsass wrappers:

How do I Consume Skeleton Sass?

If you're using a bower, npm, or yarn then install via:

# bower is deprecated
bower i --save-dev skeleton-sass
bower i --save-dev skeleton-sass-official

npm i --save-dev skeleton-sass-official

yarn add skeleton-sass-official --dev

Optionally, if you are not using one of these package managers, then you can clone the repo and put in a special directory with the rest of your dependencies.

cd path/to/my_dir
git clone https://github.com/atomicpages/skeleton-sass.git

From here, minimal stitching is required to get Skeleton Sass 3 integrated into your project! At a minimum, you need to create a single file: skeleton.scss

From *nix:

cd path/to/sass/in/project
touch skeleton.scss

From Windows:

cd path/to/sass/in/project
echo. 2>skeleton.scss

Inside of skeleton.scss we need to add our components:

@import "path/to/bower_components/normalize-scss/sass/normalize/import-now"; // import normalize-scss
@import "path/to/bower_components/skeleton-sass/skeleton/core/config"; // Skeleton Sass core loader

// import default theme variables
@import "path/to/bower_components/skeleton-sass/skeleton/themes/fresh/vars"; // theme variable overrides

// import default theme styles
@import "path/to/bower_components/skeleton-sass/skeleton/themes/fresh/include_components"; // theme base styles
@import "path/to/bower_components/skeleton-sass/skeleton/themes/fresh/grid"; // theme grid styles

Compile skeleton.scss and you now have Skeleton Sass 3 integrated into your project!

But wait! What about my themes?!

Skeleton Sass 3 makes it easy to keep your changes external to the core of Skeleton Sass with the new all-partial approach. We'll outline a sample case where we use a custom theme below:

└── src
    └── sass
        ├── skeleton.scss	 # Skeleton folder to keep file structure clean
        └── themes
            ├── _config.scss  # Global overrides and applies to all themes
            ├── _loader.scss  # Contains all of the imports
            └── my_theme
                ├── _grid.scss # Theme grid, replaces shipped grids
                ├── _include_components.scss # Includes all of the components in the components folder
                ├── _vars.scss # Theme-scoped variables and overrides
                ├── components
                │   ├── _base.scss # Default html and body styles
                │   ├── _buttons.scss
                │   ├── _forms.scss
                │   ├── _links.scss
                │   ├── _lists.scss
                │   ├── _typography.scss
                │   └── _utils.scss # Utility classes
                └── mixins
                    ├── _private.scss # Contains all "private" mixins
                    └── _public.scss # Contains all public mixins

Now that we have our sample project outlined, let's see how we can get everything working! Open _config.scss and add the following:

Note: all relative paths in the examples below fit the file structure above. If you are using a different structure, amend the paths accordingly.

@import "../../../bower_components/skeleton-sass/skeleton/core/config";

// Global var overrides

Now open _loader.scss and add the following:

@import "config";

// import theme, overrides, and extras
@import "themes/MyTheme/vars";
@import "themes/MyTheme/include_components";
@import "themes/MyTheme/grid";

Finally, open skeleton.scss and add the following as the first line of the file:

@import "skeleton/loader";

How do I load third party Sass partials into theme?

Glad you asked! Skeleton Sass 3 makes this super easy as well! Depending where you need these mixins, function, and/or variables, you can load them at the appropriate place in your _loader.scss file!

For example, let's assume we want to use font-awesome inside of our skeleton.scss file, we could modify the _loader.scss file as follows:

@import "config";

// import theme, overrides, and extras
@import "themes/MyTheme/vars";
@import "themes/MyTheme/include_components";
@import "themes/MyTheme/grid";

// import extras
@import "../../../bower_components/font-awesome/scss/font-awesome";

Note: the position of the import changes which files have access to the loaded data. For example, if you need the data in themes/MyTheme/grid then you'd need to move the import above the line where you import themes/MyTheme/grid.

Upgrading From 2.x

Skeleton Sass 3 is decently compatible to the 2.x series, but requires some manual labor (i.e. copy and pasting multiple files to the 2.x series).

Upgrading From 1.x

Skeleton Sass 2 is not backwards compatible with Skeleton Sass 1.x due to a major change in the file structure. However, we have a wiki article that explains how to upgrade from Skeleton Sass 1 to Skeleton Sass 2.

Skeleton Sass is a Sass port of Skeleton CSS. Skeleton Sass 3 decouples itself from your project so you can consume it without worrying if your package manager will clobber all of your hard work.


  1. Modular
  2. Decoupled core code
  3. Decoupled theme files for rapid theme development
  4. Extensible

Version 3 Update

After a year of working with build systems like gulp, make, gradle, and maven it became obvious that the structure of Skeleton Sass 2 didn't really promote easy updating. Most build systems have a clean task which deletes entire directories that contains artifacts, target directories, object files, etc. Skeleton Sass 2 strived to be a catch-all solution with the addition of clunky scripts to automate certain things. With the release of 2.5.3, we realized a change was needed.

Skeleton Sass 3 offers a far more portable solution in order to adapt to new ways of development using dependency management systems like bower and npm. We wanted to truly make updating Skeleton Sass have zero risk of losing all your hard work. Now contributors to your projects can simply install Skeleton Sass as a dependency and all of your changes are 100% decoupled from the core.
