There have been a number of tools to generate HTML-based slides from simple ASCII text. 20 years ago, I was a fan of Magicpoint: https://en.wikipedia.org/wiki/MagicPoint https://en.wikipedia.org/wiki/MagicPoint My recollection is that Magicpoint was really good for drafting the first version of a presentation, where you shouldn't be thinking about how it looks, but rather about what the content flow is. But fine tuning of good looking presentations was not its forte.
