Reveal JS Example appears broken

[laughingbiscuit]

Explain the problem.

Navigate to https://pandoc.org/demo/example16d.html ( the revealjs result of number 16 in https://pandoc.org/demos.html ) . The slides are not rendered correctly. The same problem persists when generated locally.

The issue looks similar to #6408 from a few years ago.

To replicate:

./pandoc/bin/pandoc -t revealjs -s -o index.html slides.md

Source markdown:

$ cat slides.md

Looks like the css sources cannot be reached e.g. https://unpkg.com/reveal.js@%5E4//dist/theme/black.css

[laughingbiscuit]

not sure if this is a temporary outage on unpkg or if srcs should be switched to another cdn e.g. https://cdnjs.com/libraries/reveal.js/4.4.0

[laughingbiscuit]

Successful workaround using jsdelivr CDN (used this as it included the expected /dist dir, unlike other CDNs):

./pandoc/bin/pandoc -t revealjs -s -o index.html slides.md -V revealjs-url=https://cdn.jsdelivr.net/npm/[email protected]

looks like it was a temporary outage.
