MathJax Syntax for Markdown

In your Markdown content, use \\(\\) delimiters for in-line mathematics.

For mathematics blocks you can use either $$$$ or \\[\\] as delimiters.

Here’s an example Markdown content:

When \\( a \ne 0 \\), there are two solutions to

$$ ax^2 + bx + c = 0 $$

and they are:

\\[ x = {-b \pm \sqrt{b^2-4ac} \over 2a} \\]

Output:

When \( a \ne 0 \), there are two solutions to

$$ ax^2 + bx + c = 0 $$

and they are:

\[x = {-b \pm \sqrt{b^2-4ac} \over 2a}\]

Customize MathJax Configuration

You can customize the default behavior of MathJax if you want.

Minimo picks up configuration for MathJax from the /data/config/mathjax.json file.

The default configuration options look like this:

{
  "library": {
    "path": "//unpkg.com/mathjax/MathJax.js",
    "config": "TeX-MML-AM_CHTML"
  },
  "config": {}
}
  • library [Object]:
    • path [String]: URL for the main MathJax.js file.
    • config [String]: Configuration file’s name/path
  • config [Object]:
    • In-line configuration options

So, if you want to tinker with it’s configuration options:

  • Create a /data/config/mathjax.json file in your site’s repository
  • Copy the default configuration options
  • Start hacking

For exmaple, if you want to enable $$ delimiters for in-line mathematics, you probably want something like this:

{
  "library": {
    "path": "//unpkg.com/mathjax/MathJax.js",
    "config": "TeX-MML-AM_CHTML"
  },
  "config": {
    "tex2jax": {
      "inlineMath": [["$", "$"], ["\\(", "\\)"]],
      "processEscapes": true
    }
  }
}
