This is an example site for Sass integration in Jekyll

You have two kinds of Sass files:

1. Main files, which you wish to be output as CSS files
2. Partials, which are used by main files in @import statements

Main files are like pages – they go where you want them to be output, and they contain the YAML front matter (--- lines) at the top. Partials are like hidden Jekyll data, so they go in an underscored directory, which defaults to _sass.

You site might look like this:

| - _sass
  | - _typography.scss
  | - _layout.scss
  | - _colors.scss
| - assets/css
  | - main.scss
  | - print.scss

And so on.

The output, in your _site directory, would look like this:

| - assets/css
  | - main.css
  | - print.css

Boom! Now you have just your SCSS/Sass converted over to CSS with all the proper inputs. See also assets section in Jekyll’s documentation.
