KaTeX can be used to render mathematical notation within articles.

Blowfish will only bundle the KaTeX assets into your project if you make use of mathematical notation. In order for this to work, simply include the [`katex` shortcode ]({{< ref "docs/shortcodes#katex" >}} ) within the article. Any KaTeX syntax on that page will then be automatically rendered.

Use the online reference of [supported TeX functions ](https://katex.org/docs/supported.html ) for the available syntax.
## Inline notation
Inline notation can be generated by wrapping the expression in `\\(` and `\\)` delimiters.
**Example:**
```tex
% KaTeX inline notation
Inline notation: \\(\varphi = \dfrac{1+\sqrt5}{2}= 1.6180339887…\\)
```
Inline notation: \\(\varphi = \dfrac{1+\sqrt5}{2}= 1.6180339887…\\)
## Block notation
Alternatively, block notation can be generated using `$$` delimiters. This will output the expression in its own HTML block.
**Example:**
```tex
% KaTeX block notation
$$
\varphi = 1+\frac{1} {1+\frac{1} {1+\frac{1} {1+\cdots} } }
$$
```
$$
\varphi = 1+\frac{1} {1+\frac{1} {1+\frac{1} {1+\cdots} } }
$$
