 The example we will use will be an article on Oslo, whose front matter should be set to exactly the same name as the corresponding file name in `data/locations/`:
 
-```

 The content of `oslo.toml` can be accessed from your template using the following node path: `.Site.Data.locations.oslo`. However, the specific file you need is going to change according to the front matter.

 The variable for `.Params.location` is a string and can therefore replace `oslo` in the example above:
 
-```
+```go-html-template
 {{ index .Site.Data.locations .Params.location }}
 => map[website:https://www.oslo.kommune.no pop_city:658390 pop_metro:1717900]
 ```
 
 Now the call will return the specific file according to the location specified in the content's front matter, but you will likely want to write specific properties to the template. You can do this by continuing down the node path via dot notation (`.`):
 
-```
+```go-html-template
 {{ (index .Site.Data.locations .Params.location).pop_city }}
 => 658390
