Paginated html output (inspired by pagedown)

[GitHunter0]

Description

Hi folks, it would be amazing to have in Quarto a feature like pagedown, which provides a paginated html output.

Benefits:

• Html with pages like a real document / article / book
• Table of contents with page numbers. See https://pagedown.rbind.io/
• Easy conversion into PDFs without LaTeX installation

I believe it's the only thing that R Markdown still gets an edge over Quarto.

Thank you.
