-The `Ordinal` method returns the zero-based ordinal of the shortcode in relation to its parent. If the parent is the page itself, the ordinal represents the position of this shortcode in the page content.
-
-This method is useful for, among other things, assigning unique element IDs when a shortcode is called two or more times from the same page. For example:
-
-{{< code file=content/about.md lang=md >}}
-{{</* img src="images/a.jpg" */>}}
-
-{{</* img src="images/b.jpg" */>}}
-{{< /code >}}
-
-This shortcode performs error checking, then renders an HTML `img` element with a unique `id` attribute:
-
-{{< code file=layouts/shortcodes/img.html  >}}
-{{ $src := "" }}
-{{ with .Get "src" }}
-  {{ $src = . }}
-  {{ with resources.Get $src }}
-    {{ $id := printf "img-%03d" $.Ordinal }}
-    <img id="{{ $id }}" src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
-  {{ else }}
-    {{ errorf "The %q shortcode was unable to find %s. See %s" $.Name $src $.Position }}
-  {{ end }}
-{{ else }}
-  {{ errorf "The %q shortcode requires a 'src' parameter. See %s" .Name .Position }}
-{{ end }}
-{{< /code >}}
-
-Hugo renders the page to:
-
-```html
-<img id="img-000" src="/images/a.jpg" width="600" height="400" alt="">
-<img id="img-001" src="/images/b.jpg" width="600" height="400" alt="">
-```

-In the shortcode template above, the [`with`] statement is used to create conditional blocks. Remember that the `with` statement binds context (the dot) to its expression. Inside of a `with` block, preface shortcode method calls with a `$` to access the top level context passed into the template.
