title: Code Blocks
---
There are several ways to add code blocks. Most of them work out of the box, only the Hugo shortcode `<highlight>` needs to be configured to work properly. The theme also provides some additional features like a copy button and an option to set the maximum length of code blocks. Both of these functions and the dependent formatting rely on the `.highlight` CSS class. You must ensure that you always assign a language to your code blocks if you want to use these functions. If you do not want to apply syntax highlighting, you can also specify `plain` or `text` as the language.
{{< toc >}}
## Inline code
To display an inline shortcode use single quotes:
```plain
`some code`
```
**Example:** `some code` with a [`link`](#)
## Code blocks
Code blocks can be uses without language specification:
````markdown
```plain
some code
```
````
**Example:**
```plain
some code
```
... or if you need language specific syntax highlighting:
````markdown
```shell
# some code
echo "Hello world"
```
````
**Example:**
```shell
# some code
echo "Hello World"
```
## Highlight shortcode
Hugo has a build-in shortcode for syntax highlighting. To work properly with this theme, you have to set following options in your site configuration:
{{< tabs "uniqueid" >}}
{{< tab "TOML" >}}
```toml
pygmentsUseClasses=true
pygmentsCodeFences=true
```
{{< /tab >}}
{{< tab "YAML" >}}
```yaml
pygmentsUseClasses: true
pygmentsCodeFences: true
```
{{< /tab >}}
{{< /tabs >}}
You can use it like every other shortcode:
<!-- prettier-ignore -->
```markdown
{{</* highlight Shell "linenos=table" */>}}
# some code
echo "Hello World"
{{</* /highlight */>}}
```
**Example:**
<!-- prettier-ignore-start -->
<!-- markdownlint-capture -->
<!-- markdownlint-disable -->
{{< highlight Shell "linenos=table" >}}
# some code
echo "Hello World"
{{< /highlight >}}
<!-- markdownlint-restore -->
<!-- prettier-ignore-end-->
## Gist Shortcode
The Gist shortcode is a built-in Hugo shortcode to load GitHub gists. For details usage information please check the Hugo [documentation](https://gohugo.io/content-management/shortcodes/#gist).
<!-- prettier-ignore -->
```markdown
{{</* gist spf13 7896402 */>}}
```
**Example:**
{{< gist spf13 7896402 >}}
