Params	Returns a map of custom parameters as defined in the site configuration.			related returnType signatures functions/collections/indexFunction methods/page/Params methods/page/Param maps.Params SITE.Params

With this site configuration:

{{< code-toggle file=hugo >}} [params] subtitle = 'The Best Widgets on Earth' copyright-year = '2023' [params.author] email = 'jsmith@example.org' name = 'John Smith' [params.layouts] rfc_1123 = 'Mon, 02 Jan 2006 15:04:05 MST' rfc_3339 = '2006-01-02T15:04:05-07:00' {{< /code-toggle >}}

Access the custom parameters by chaining the identifiers:

{{ .Site.Params.subtitle }} → The Best Widgets on Earth
{{ .Site.Params.author.name }} → John Smith

{{ $layout := .Site.Params.layouts.rfc_1123 }}
{{ .Site.Lastmod.Format $layout }} → Tue, 17 Oct 2023 13:21:02 PDT

In the template example above, each of the keys is a valid identifier. For example, none of the keys contains a hyphen. To access a key that is not a valid identifier, use the index function:

{{ index .Site.Params "copyright-year" }} → 2023
