Add Math to your Markdown
|
|
|
|
KaTeX is fast. This plugin makes it easy to support it in your markdown.
|
|
|
|
## Usage
|
|
|
|
```
|
|
npm install markdown-it-katex
|
|
```
|
|
|
|
Include the KaTeX stylesheet in your html:
|
|
```html
|
|
<link rel="stylesheet"href="//cdnjs.cloudflare.com/ajax/libs/KaTeX/0.3.0/katex.min.css">
|
|
```
|
|
|
|
If you're using the default markdown-it parser, I also recommend the github stylesheet:
|
|

|
|
|
|
## Examples
|
|
|
|
### Inline
|
|
Surround your LaTeX with a single `$` on each side for inline rendering.
|
|
```
|
|
$\sqrt{3x-1}+(1+x)^2$
|
|
```
|
|
|
|
### Block
|
|
Use two (`$$`) for block rendering. This mode uses bigger symbols and centers
|
|
the result.
|
|
|
|
```
|
|
$$\begin{array}{c}
|
|
|
|
\nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} &
|
|
= \frac{4\pi}{c}\vec{\mathbf{j}} \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\
|
|
|
|
\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\
|
|
|
|
\nabla \cdot \vec{\mathbf{B}} & = 0
|
|
|
|
\end{array}$$
|
|
```
|
|
|
|
## Math Syntax Support
|
|
|
|
KaTeX is based on TeX and LaTeX. Support for both is growing. Here's a list of
|
|
currently supported functions:
