To enable MathJax equation rendering, set the variable `mathjax` to `true` in
the `extra` section of your config.toml. Set `mathjax_dollar_inline_enable` to
`true` to render inline math by surrounding them inside $..$.
```toml
[extra]
mathjax = true
mathjax_dollar_inline_enable = true
```
## Config
### Customize `<meta/>` tags
The following TOML and YAML code will yiled two `<meta/>` tags, `<meta property="og:title" content="the og title"/>`, `<meta property="og:description" content="the og description"/>`.
TOML:
```toml
title = "post title"
description = "post desc"
date = "2023-01-01"
[extra]
meta = [
{property = "og:title", content = "the og title"},
{property = "og:description", content = "the og description"},
]
```
YAML:
```yaml
title: "post title"
description: "post desc"
date: "2023-01-01"
extra:
meta:
- property: "og:title"
content: "the og title"
- property: "og:description"
content: "the og description"
```
If the `og:title`, the `og:description`, or the "description" are not set, the page's title and description will be used. That is, the following TOML code generates `<meta property="og:title" content="post title"/>`, `<meta property="og:description" content="post desc"/>`, and `<meta property="og:description" content="post desc"/>` as default values.
