Beamer frame attributes using horizontal rules in Quarto

[DavidJesse21]

Hi,

I just stumbled across an issue regarding the usage of frame attributes for beamer output in combination with the usage of horizontal rules in Quarto (---).
Since I want to have a slide without a title, I used the horizontal rule.
At the same time I needed the fragile frame attribute.
For a slide with a title I would just type ## Slide tile {.fragile}.
However, I am not sure how or if adding frame attributes works for slides created with a horizontal rule.
Apparently, --- {.fragile} does not work.
Does anyone have an idea, how I could make this work?

Cheers
David

Use an empty title.

## {.fragile}
