If you need inspiration you can take a look at this as well made using REXPaint. https://preview.redd.it/vxfohcwxywt71.png?width=1458&format=...
It's all ASCII art so in theory one should be able to convert it to HTML. I have a project to make a story using REXPaint to HTML in a near future.
If you need more info, feel free to contat me raising an issue on github.
I can totally relate to it but it might be because I'm in a mid life crisis.
