Sass support

To use Sass in your Vue application, you need to install the sass package:

npm install -D sass

Then, you can use the lang="scss" attribute in the <style> tag of your Vue files:

app.vue
<style lang="scss">
  $primary-color: #3498db;

  div {
    span {
      color: $primary-color;
    }
  }
  </style>
