The `{{body_class}}` helper outputs different classes on different pages, depending on what context the page belongs to. For example the home page will get the class `.home-template`, but a single post page would get `.post-template`. Ghost provides a series of both static and dynamic `body_class` classes: #### Static classes * `home-template` – The class applied when the template is used for the home page * `post-template` – The class applied to all posts * `page-template` – The class applied to all pages * `tag-template` – The class applied to all tag index pages * `author-template` – The class applied to all author pages * `private-template` – The class applied to all page types when password protected access is activated #### Dynamic classes * `page-{slug}` – A class of `page-` plus the page slug added to all pages * `tag-{slug}` – A class of `tag-` plus the tag page slug added to all tag index pages * `author-{slug}` – A class of `author-` plus the author page slug added to all author pages ### Examples ```handlebars theme={"dark"} ... ... {{{body}}} ... ```
