Reveal.js Presentation: how to set background for slides without title?

[aborruso]

Hi,
in the manual I have "You can apply full page backgrounds outside of the slide area by adding a background attribute to your slide headers", then I must a title, something like ## Slide Title {background-color="aquamarine"}

How to apply a background color to a slide without any title?

Thank you

You can do this by using empty header

---
title: "A title"
author: "me"
format:
  revealjs:
    theme: dark
---

## {background-color="aquamarine"}

Hello World

You could open a PR but I am not sure where is the best place to add this. This will happen not only with background-color but any attributes that should be on header. Maybe have something about no-title slide 🤔

But thanks for opening this question as it will at least serve as documentation if anyone else have the same question.

I think we could add a clarification right where @aborruso started, on https://quarto.org/docs/presentations/revealjs/#slide-backgrounds, since this is likely to be a common case for it to come up.

The clarification is up. Thanks for the suggestion!
