Mathematical notation in a Hugo project can be enabled by using third party JavaScript libraries.

|
||
|
|
|
||
|
|
In this example we will be using [KaTeX](https://katex.org/)
|
||
|
|
|
||
|
|
- Create a partial under `/layouts/partials/math.html`
|
||
|
|
- Within this partial reference the [Auto-render Extension](https://katex.org/docs/autorender.html) or host these scripts locally.
|
||
|
|
- Include the partial in your templates like so:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
{{ if or .Params.math .Site.Params.math }}
|
||
|
|
{{ partial "math.html" . }}
|
||
|
|
{{ end }}
|
||
|
|
```
|
||
|
|
|
||
|
|
- To enable KaTex globally set the parameter `math` to `true` in a project's configuration
|
||
|
|
- To enable KaTex on a per page basis include the parameter `math: true` in content files
|
||
|
|
|
||
|
|
**Note:** Use the online reference of [Supported TeX Functions](https://katex.org/docs/supported.html)
|

{{< math.inline >}}
|
||
|
|
{{ if or .Page.Params.math .Site.Params.math }}
|
||

### Examples
|
||
|
|
|
||
|
|
{{< math.inline >}}
|
||
|
|
<p>
|
||
|
|
Inline math: \(\varphi = \dfrac{1+\sqrt5}{2}= 1.6180339887…\)
|
||
|
|
</p>
|
||
|
|
{{</ math.inline >}}
|
||
|
|
|
||
|
|
Block math:
|
||
|
|
$$
|
||
|
|
\varphi = 1+\frac{1} {1+\frac{1} {1+\frac{1} {1+\cdots} } }
|
||
|
|
$$
