+title: Params
+description: Returns a map of custom parameters as defined in the front matter of the given page.
+categories: []
+keywords: []

+ returnType: maps.Params
+ signatures: [PAGE.Params]

+
+With this front matter:
+
+{{< code-toggle file=content/news/annual-conference.md >}}
+title = 'Annual conference'
+date = 2023-10-17T15:11:37-07:00
+display_related = true
+event-date = '2023'
+[params.author]
+ email = 'jsmith@example.org'
+ name = 'John Smith'
+{{< /code-toggle >}}
+
+The `title` and `date` fields are standard parameters---the other fields are user-defined.
+
+Access the custom parameters by [chaining] the [identifiers]:
+
+```go-html-template
+{{ .Params.display_related }} → true
+{{ .Params.author.name }} → John Smith
+```
+
+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:
+
+```go-html-template
+{{ index .Params "event-date" }} → 2023
+```
