This is a new feature in 1.2.0.

You have to enable it manually in config.

## Enable for single page (recommended)

Add `enableMathJax: true` in the front matter of the page.

Notice: please ensure you didn't set `enableMathJax` globally.

## Globally Enabling

Add `enableMathJax=true` to the section of `[param]` in your `config.toml`.
