Inner	Returns the content between opening and closing shortcode tags, applicable when the shortcode call includes a closing tag.			related returnType signatures functions/strings/Trim methods/page/RenderString functions/transform/Markdownify methods/shortcode/InnerDeindent template.HTML SHORTCODE.Inner

This content:

{{< code file=content/services.md lang=md >}} {{</* card title="Product Design" />}} We design the best widgets in the world. {{</ /card */>}} {{< /code >}}

With this shortcode:

{{< code file=layouts/shortcodes/card.html >}}

{{ with .Get "title" }}

{{ . }}

{{ end }}

{{ .Inner | strings.TrimSpace }}

{{< /code >}}

Is rendered to:

<div class="card">
  <div class="card-title">Product Design</div>
  <div class="card-content">
    We design the **best** widgets in the world.
  </div>
</div>

{{% note %}} Content between opening and closing shortcode tags may include leading and/or trailing newlines, depending on placement within the Markdown. Use the strings.TrimSpace function as shown above to remove both carriage returns and newlines.

{{% /note %}}

{{% note %}} In the example above, the value returned by Inner is Markdown, but it was rendered as plain text. Use either of the following approaches to render Markdown to HTML. {{% /note %}}

Use the RenderString method

Let's modify the example above to pass the value returned by Inner through the RenderString method on the Page object:

{{< code file=layouts/shortcodes/card.html >}}

{{ with .Get "title" }}

{{ . }}

{{ end }}

{{ .Inner | strings.TrimSpace | .Page.RenderString }}

{{< /code >}}

Hugo renders this to:

<div class="card">
  <div class="card-title">Product design</div>
  <div class="card-content">
    We produce the <strong>best</strong> widgets in the world.
  </div>
</div>

You can use the markdownify function instead of the RenderString method, but the latter is more flexible. See details.

Use alternate notation

Instead of calling the shortcode with the {{</* */>}} notation, use the {{%/* */%}} notation:

{{< code file=content/services.md lang=md >}} {{%/* card title="Product Design" /%}} We design the best widgets in the world. {{%/ /card */%}} {{< /code >}}

When you use the {{%/* */%}} notation, Hugo renders the entire shortcode as Markdown, requiring the following changes.

First, configure the renderer to allow raw HTML within Markdown:

{{< code-toggle file=hugo >}} [markup.goldmark.renderer] unsafe = true {{< /code-toggle >}}

This configuration is not unsafe if you control the content. Read more about Hugo's security model.

Second, because we are rendering the entire shortcode as Markdown, we must adhere to the rules governing indentation and inclusion of raw HTML blocks as provided in the CommonMark specification.

{{< code file=layouts/shortcodes/card.html >}}

{{ with .Get "title" }}

{{ . }}

{{ end }}

{{ .Inner | strings.TrimSpace }}

{{< /code >}}

The difference between this and the previous example is subtle but required. Note the change in indentation, the addition of a blank line, and removal of the RenderString method.
