-See [Template Lookup](/templates/lookup-order/).

-## Example single page templates
-
-Content pages are of the type `page` and will therefore have all the [page variables][pagevars] and [site variables] available to use in their templates.
-
-### `posts/single.html`
-
-This single page template makes use of Hugo [base templates], the [`.Format` function] for dates, the [`.WordCount` page variable][pagevars], and ranges through the single content's specific [taxonomies][pagetaxonomy]. [`with`] is also used to check whether the taxonomies are set in the front matter.
