How to add MathJax support to Zola Static Site Generator

gistfile1.txt

Step 1: follow the instructions on this [starting guide](https://www.getzola.org/documentation/getting-started/overview/)
Step 2: add following piece of code in templates/blog-page.html (before the last line):

```
{% if page.extra.math %}
<script>
  MathJax = {
    tex: {
      inlineMath: [['$', '$'], ['\\(', '\\)']]
    }
  };
</script>
<script type="text/javascript" async
  src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-chtml.js">
</script>
{% endif %}
```

Step 3: In the head of each post markdown file, add two lines:

```
[extra]
math = true
```

Then you can use MathJax latex expressions in the markdown posts. 

Note: Single $ for inline math, $$ for block math, \newline for new line break.
