    /**
    * Components > Page Banner
    * =================================
    * Page Banners stretch to the full width of their container and contain banner images which typically use a `picture` element.
    * Optionally they can display a white or coloured version of the Just Eat rays at the bottom.
    *
    * Example: Menu – Cuisine image at top of page.
    *
    * The `c-pageBanner` component is an optional mixin within Fozzie.
    * If you'd like to use it in your project you can include it by adding `@include pageBanner();` into your SCSS dependencies file.
    *
    * Documentation:
    * https://fozzie.just-eat.com/styleguide/ui-components/page-banner
