Title	Returns the title of the given page.			functions_and_methods returnType signatures string PAGE.Title

With pages backed by a file, the Title method returns the title field as defined in front matter:

{{< code-toggle file=content/about.md fm=true >}} title = 'About us' {{< /code-toggle >}}

{{ .Title }} → About us

When a page is not backed by a file, the value returned by the Title method depends on the page kind.

Page kind	Page title when the page is not backed by a file
home	site title
section	section name (capitalized and pluralized)
taxonomy	taxonomy name (capitalized and pluralized)
term	term name (capitalized and pluralized)

You can disable automatic capitalization and pluralization in your site configuration:

{{< code-toggle file=hugo >}} capitalizeListTitles = false pluralizeListTitles = false {{< /code-toggle >}}

You can change the capitalization style in your site configuration to one of ap, chicago, go, firstupper, or none. For example:

{{< code-toggle file=hugo >}} titleCaseStyle = "firstupper" {{< /code-toggle >}}
