MathJax Configuration

Create or extend _includes/head_custom.html with:

{% assign math = page.math | default: layout.math | default: site.math %}

{% case math %}
  {% when "mathjax" %}
    {% include mathjax.html %}
{% endcase %}

Copy the following files to your website source repo:
To make MathJax available on all your web pages, add to _config.yml:
```
math: mathjax
```
To restrict MathJax to pages that use it, add to the front matter either:
```
math: mathjax
```
or:
```
layout: mathjax
```
You can add a preamble of MathJax definitions of new commands and environments in _layouts/mathjax.html. It extends the default layout.

MathJax options

You can customise MathJax by adding further options in _includes/mathjax.html.
