{{% note %}}
To override Hugo's embedded `comment` shortcode, copy the [source code] to a file with the same name in the `layouts/shortcodes` directory.
[source code]: {{% eturl comment %}}
{{% /note %}}
{{< new-in "0.137.1" >}}
Use the `comment` shortcode to include comments in your content. Hugo will ignore the text within these comments when rendering your site.
Use it inline:
```text
{{%/* comment */%}} rewrite the paragraph below {{%/* /comment */%}}
```
Or as a block comment:
```text
{{%/* comment */%}}
rewrite the paragraph below
{{%/* /comment */%}}
```
Although you can call this shortcode using the `{{</* */>}}` notation, computationally it is more efficient to call it using the `{{%/* */%}}` notation as shown above.

{{% note %}}
To override Hugo's embedded `details` shortcode, copy the [source code] to a file with the same name in the `layouts/shortcodes` directory.
[source code]: {{% eturl details %}}
{{% /note %}}
## Example
With this markup:
```text
{{</* details summary="See the details" */>}}
This is a **bold** word.
{{</* /details */>}}
```
Hugo renders this HTML:
```html
<details>
<summary>See the details</summary>
<p>This is a <strong>bold</strong> word.</p>
</details>
```
Which looks like this in your browser:
{{< details summary="See the details" >}}
This is a **bold** word.
{{< /details >}}
## Parameters
summary
: (`string`) The content of the child `summary` element rendered from Markdown to HTML. Default is `Details`.
open
: (`bool`) Whether to initially display the content of the `details` element. Default is `false`.
class
: (`string`) The `class` attribute of the `details` element.
name
: (`string`) The `name` attribute of the `details` element.
title
: (`string`) The `title` attribute of the `details` element.
## Styling
Use CSS to style the `details` element, the `summary` element, and the content itself.
```css
/* target the details element */
details { }
/* target the summary element */
details > summary { }
/* target the children of the summary element */
details > summary > * { }
/* target the content */
details > :not(summary) { }

{{% note %}}
To override Hugo's embedded `figure` shortcode, copy the [source code] to a file with the same name in the `layouts/shortcodes` directory.
[source code]: {{% eturl figure %}}
{{% /note %}}
## Example
With this markup:
```text
{{</* figure
src="/images/examples/zion-national-park.jpg"
alt="A photograph of Zion National Park"
link="https://www.nps.gov/zion/index.htm"
caption="Zion National Park"
class="ma0 w-75"
*/>}}
```
Hugo renders this HTML:
```html
<figure class="ma0 w-75">
<a href="https://www.nps.gov/zion/index.htm">
<img
src="/images/examples/zion-national-park.jpg"
alt="A photograph of Zion National Park"

```
Which looks like this in your browser:

alt="A photograph of Zion National Park"
link="https://www.nps.gov/zion/index.htm"
caption="Zion National Park"
class="ma0 w-75"
>}}
## Parameters
src
: (`string`) The `src` attribute of the `img` element. Typically this is a [page resource](g) or a [global resource](g).
alt
: (`string`) The `alt` attribute of the `img` element.
width
: (`int`) The `width` attribute of the `img` element.
height
: (`int`) The `height` attribute of the `img` element.
loading
: (`string`) The `loading` attribute of the `img` element.
class
: (`string`) The `class` attribute of the `figure` element.
link
: (`string`) The `href` attribute of the anchor element that wraps the `img` element.
target
: (`string`) The `target` attribute of the anchor element that wraps the `img` element.
rel
: (`rel`) The `rel` attribute of the anchor element that wraps the `img` element.
title
: (`string`) Within the `figurecaption` element, the title is at the top, wrapped within an `h4` element.
caption
: (`string`) Within the `figurecaption` element, the caption is at the bottom and may contain plain text or markdown.
attr
: (`string`) Within the `figurecaption` element, the attribution appears next to the caption and may contain plain text or markdown.
attrlink
: (`string`) The `href` attribute of the anchor element that wraps the attribution.
## Image location
The `figure` shortcode resolves internal Markdown destinations by looking for a matching [page resource](g), falling back to a matching [global resource](g). Remote destinations are passed through, and the render hook will not throw an error or warning if unable to resolve a destination.
You must place global resources in the `assets` directory. If you have placed your resources in the `static` directory, and you are unable or unwilling to move them, you must mount the `static` directory to the `assets` directory by including both of these entries in your site configuration:
{{< code-toggle file=hugo >}}
[[module.mounts]]
source = 'assets'
target = 'assets'
[[module.mounts]]
source = 'static'
target = 'assets'
{{< /code-toggle >}}

title: Highlight
description: Insert syntax-highlighted code into your content using the highlight shortcode.
categories: [shortcodes]
keywords: []
menu:
docs:
parent: shortcodes
weight:
weight:
toc: true
---
{{% note %}}
To override Hugo's embedded `highlight` shortcode, copy the [source code] to a file with the same name in the `layouts/shortcodes` directory.
[source code]: {{% eturl highlight %}}
{{% /note %}}
{{% note %}}
With the Markdown [content format], the `highlight` shortcode is rarely needed because, by default, Hugo automatically applies syntax highlighting to fenced code blocks.
The primary use case for the `highlight` shortcode in Markdown is to apply syntax highlighting to inline code snippets.
[content format]: /content-management/formats/
{{% /note %}}
The `highlight` shortcode calls the [`transform.Highlight`] function which uses the [Chroma] syntax highlighter, supporting over 200 languages with more than 40 [available styles].
[chroma]: https://github.com/alecthomas/chroma
[available styles]: https://xyproto.github.io/splash/docs/
[`transform.Highlight`]: /functions/transform/highlight/
## Arguments
The `highlight` shortcode takes three arguments.
```text
{{</* highlight LANG OPTIONS */>}}
CODE
{{</* /highlight */>}}
```
CODE
: (`string`) The code to highlight.
LANG
: (`string`) The language of the code to highlight. Choose from one of the [supported languages]. This value is case-insensitive.
OPTIONS
: (`string`) Zero or more space-separated key-value pairs wrapped in quotation marks. Set default values for each option in your [site configuration]. The key names are case-insensitive.
[site configuration]: /getting-started/configuration-markup#highlight
[supported languages]: /content-management/syntax-highlighting/#list-of-chroma-highlighting-languages
## Example
```text
{{</* highlight go "linenos=inline, hl_Lines=3 6-8, style=emacs" */>}}
package main
import "fmt"
func main() {
for i := 0; i < 3; i++ {
fmt.Println("Value of i:", i)
}
}
{{</* /highlight */>}}
```
Hugo renders this to:
{{< highlight go "linenos=inline, hl_Lines=3 6-8, noClasses=true" >}}
package main
import "fmt"
func main() {
for i := 0; i < 3; i++ {
fmt.Println("Value of i:", i)
}
}
{{< /highlight >}}
You can also use the `highlight` shortcode for inline code snippets:
```text
This is some {{</* highlight go "hl_inline=true" */>}}fmt.Println("inline"){{</* /highlight */>}} code.
```
Hugo renders this to:
This is some {{< highlight go "hl_inline=true, noClasses=true" >}}fmt.Println("inline"){{< /highlight >}} code.
Given the verbosity of the example above, if you need to frequently highlight inline code snippets, create your own shortcode using a shorter name with preset options.
{{< code file=layouts/shortcodes/hl.html >}}
{{ $code := .Inner | strings.TrimSpace }}
{{ $lang := or (.Get 0) "go" }}
{{ $opts := dict "hl_inline" true "noClasses" true }}
{{ transform.Highlight $code $lang $opts }}
{{< /code >}}
```text
This is some {{</* hl */>}}fmt.Println("inline"){{</* /hl */>}} code.
```
Hugo renders this to:
This is some {{< hl >}}fmt.Println("inline"){{< /hl >}} code.
## Options
Pass the options when calling the shortcode. You can set their default values in your [site configuration].

To override Hugo's embedded `qr` shortcode, copy the [source code] to a file with the same name in the `layouts/shortcodes` directory.
[source code]: {{% eturl qr %}}
{{% /note %}}
The `qr` shortcode encodes the given text into a [QR code] using the specified options and renders the resulting image.
Internally this shortcode calls the `images.QR` function. Please read the [related documentation] for implementation details and guidance.
[QR code]: https://en.wikipedia.org/wiki/QR_code
[related documentation]: /functions/images/qr/
## Examples
Use the self-closing syntax to pass the text as an argument:
```text
{{</* qr text="https://gohugo.io" /*/>}}
```
Or insert the text between the opening and closing tags:
```text
{{</* qr */>}}
https://gohugo.io
{{</* /qr */>}}
```
Both of the above produce this image:
{{< qr text="https://gohugo.io" class="qrcode" />}}
To create a QR code for a phone number:
```text
{{</* qr text="tel:+12065550101" /*/>}}
```
{{< qr text="tel:+12065550101" class="qrcode" />}}
To create a QR code containing contact information in the [vCard] format:
[vCard]: https://en.wikipedia.org/wiki/VCard
```text
{{</* qr level="low" scale=2 alt="QR code of vCard for John Smith" */>}}
