 **Note:** these media types are configured for **your output formats**. If you want to redefine one of Hugo's default output formats (e.g. `HTML`), you also need to redefine the media type. So, if you want to change the suffix of the `HTML` output format from `html` (default) to `htm`:
 
-```toml
+{{< code-toggle file="config" >}}
 [mediaTypes]
-[mediaTypes."text/html"]
-suffixes = ["htm"]
+  [mediaTypes."text/html"]
+    suffixes = ["htm"]
 
 # Redefine HTML to update its media type.
 [outputFormats]
-[outputFormats.HTML]
-mediaType = "text/html"
-```
+  [outputFormats.HTML]
+    mediaType = "text/html"
+{{</ code-toggle >}}
 
 **Note** that for the above to work, you also need to add an `outputs` definition in your site config.
