You can create Style guides to allow specific aspects of your Site Studio styles and templates to be managed from within the Drupal theme settings page (Appearance > Settings > "Theme"). You can think of style guides as theme overrides.

A Style guide is a form. The fields within the form are exposed as Drupal tokens. These token can be used in-place of static values within your Site Studio styles and templates. The values of the tokens will be used when your styles and templates are generated.
