//         padding-left: $spacing-unit / 2;
//     }
// }

@mixin media-query($device) {
    @media screen and (max-width: $device) {
        @content;
    }
}
// Import partials from `sass_dir` (defaults to `_sass`)
@import "base", "layout", "syntax-highlighting";

I need to fix the top YAML comment. I can also auto-detect this as YAML Front Matter by checking for the YAML comment at the top after the code sample is identified as a CSS variant.
