Add Information About How to Customize the Logo in Reveal.js

[RoyiAvital]

In a presentation mode based on revealjs there is an option to define a logo and a footer.
I think it would be great to add a documentation on how to customize the logo:

1. Size.
2. Location.
3. Link (I want that a click on the image will link to a URL).

It would also be beneficial to remind that the footer field might be treated as a MarkDown text.

All (at least size and location) that are CSS based modifications.

For example: https://github.com/mcanouil/quarto-revealjs-coeos/blob/main/_extensions/coeos.scss will produce:

I have seen those. I was looking for something on the ReavelJS mode.

Then, there is the revealjs website (https://revealjs.com/) which is comprehensive.

But the logo and footer are properties of Quarto, not the RevealJS. I wonder where to see the CSS Quarto uses. Where it parses the logo variable. Etc...

Take a look at the source code: https://github.com/quarto-dev/quarto-cli/tree/main/src/format/reveal and associated resources https://github.com/quarto-dev/quarto-cli/tree/main/src/resources/formats/revealjs

Also, you can still use JS to customise, i.e., remove the logo on title slide as described in the following issue quarto-dev/quarto-cli#1391
