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
body_classes: "header-dark header-transparent"On a particular page will ensure that page has those options enabled (assuming they are false by default).
Hero Options
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.
