The Quark theme has the ability to allow pages to override some of the default options by letting the user set
body_classes for any page. The theme will merge the combination of the defaults with any
body_classes set. This allows you to easily add hero classes to give your blog post some bling.
body_classes: "header-dark header-transparent"
On a particular page will ensure that page has those options enabled (assuming they are false by default).
The hero template allows some options to be set in the page frontmatter. This is used by the modular
hero as well as the blog and item templates to provide a more dynamic header.
