I admit this might be a bit niche.

I like using this theme: https://github.com/dzello/revealjs-themes#sunblind

To get the bold border, 

>   1. Add 4 divs to your HTML page:
```html
    <div class="line top"></div>
    <div class="line bottom"></div>
    <div class="line left"></div>
    <div class="line right"></div>+
```

How do I override the basic template to add those? If I add them from the qmd file, they're not at the right level (they have to come after the div "slides").
