How to set a font family for highlighjs component

I tried using CSS to set a font family for highlighted code ,but it didn‘t work.
I was confused because it seems that there is not an official way to set a font family for highlightJS
When I using native highlightJS and `

`, `.hljs` it works


```css

/* a div contained a highlightjs component */

#box{

  font-family: 'JetBrainsMono-Regular';

}

.highlightjs {

  font-family: 'JetBrainsMono-Regular';

}

.hljs {

  font-family: 'JetBrainsMono-Regular';

}

```
