Reversed animations in HTML slides

[alex44119]

I've guessed (thanks to this commit 336) that reverse animation aren't available for html.

My question is : Why ?
(and if it is indeed possible, I need some help to make it work for me)

Thanks a lot for your job,

Hi Hugo, thanks for your question!

#336 didn't do anything about supporting reversed animations inside HTML slides: it only removed them from the output folder as they were never used.

The support of reversed animation is something non-standard, and it is only provided by the default (i.e., manim-slides present ...) viewer, because I wrote it. I didn't write RevealJS (the

You could raise an issue on their repository (https://github.com/hakimel/reveal.js), but I doubt this is a feature they might want to add.

However, something we could do is include inside the HTML template a JS script that listens to keystrokes (e.g., with https://revealjs.com/keyboard/) and modifies the background video to include the reversed animation instead.

I'll mark this a nice feature to have, but I don't have much time to work on this at the moment, but feel free to give it a try (or anybody else)!
