Since v4.2.0, Terminal Theme uses Chroma as syntax highlighter. As Hugo documentation refers: "it is built in Go and is really, really fast".
Below you can see many basic presentations of the code blocks you can use depending on your needs. Except the `{{ < code > }}` shortcode example, all other blocks are generated based on the configuration you can learn about from the [official Hugo docs](https://gohugo.io/content-management/syntax-highlighting/).
---
## Examples:
### Raw block with no specified language (and no syntax highlighting)
```
Example HTML5 Document
Test
```
### With specified language
#### Line highlighting
```html {hl_lines=[5]}
Example HTML5 Document
Test
```
#### Line highlighting / table line numbers
```html {linenos=table,hl_lines=[5]}
Example HTML5 Document
Test
```
#### Line highlighting / inline line numbers
```html {linenos=inline,hl_lines=[5]}
Example HTML5 Document
Test
```
#### Hugo's internal `{{ < highlight > }}` shortcode
{{< highlight html >}}
Example HTML5 Document
Test
{{< /highlight >}}
#### Custom built-in `{{ < code > }}` shortcode
{{< code title="Hey, this is a code block title" language="html" open="true" opts="linenos=table" >}}
Example HTML5 Document
Test
{{< /code >}}
