KaTeX can be used to render mathematical notation within articles.
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
{{< katex >}}
|
||
|
|
|
||
|
|
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. Example below:
|
||
|
|
|
||
|
|
```md
|
||
|
|
{{</* katex */>}}
|
||
|
|
```
|
||
|
|
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} } }
|
||
|
|
$$
