What are partials in SCSS (Sass)?

What are partials?

Sass has few really good way to add file and divide your overall code in modules.

Partials are the the modules with their name starting with an underscore.

You use partials in SassScript when you want to skip the compilation of those files and just add those stylesheets as modules only.

Foe e.g.

_code.scss

When SassScript sees that initial underscore, it understands not to compile those files on their own.

You don’t need to add the underscore while importing those modules.

Just like this:

@import 'partials/code.scss';

What about index.scss?

SassScript automatically recognizes _index files from a folder.

So, if you add a folder name then it will look for _index.scss or _index.sass files and will load them automatically.

Example

// foundation/_fonts.scss
code {
  padding: .25em;
  line-height: 0;
}

// foundation/_lists.scss
ul, ol {
  text-align: left;

  & & {
    padding: {
      bottom: 0;
      left: 0;
    }
  }
}

// foundation/_index.scss
@use 'code';
@use 'lists';

// style.scss
@use 'foundation';

Can you load .css files in SCSS or Sass files?

Yes, SassScript can load a plain CSS file into SCSS or Sass files too. Although, they won’t be allowed any Sass special features so they can not expose any Sass members.

Just like this:

// code.css
code {
  padding: .25em;
  line-height: 0;
}

// style.scss
@use 'code';
