I cannot reproduce any font change.

I don't thing there is a bug here even with the "different animation".

I cannot reproduce any font change.

Thank you for your quick reply. I can clearly see the font change in your screenshots because the font changed from sans-serif to serif and 0,=,* look different.

I tried the revealjs demo and there's no font change during pdf export and the line highlighting works.

About the overwrite, this is an issue in Revealjs, fixed in 4.6

https://github.com/hakimel/reveal.js/issues/2867 (https://github.com/hakimel/reveal.js/commit/edf6638065bf8c10a73e8823d437cc1de356b6aa)

We'll update to v5 for next release, so it should fix it.

For the highlighting, Quarto does not use the same tool that reveal, so maybe we need to add some specific CSS rules to the print version. We'll see that after v5 update.
