Interesting. But can it do collapsible text? Didn't see it any mention in the article. It is so annoying on markdown having to use HTML to do it...
apparently it can ! https://docs.asciidoctor.org/asciidoc/latest/blocks/collapsible/
That's it, I am sold.
Collapsible text isn't very well-standardized on the web itself. A lot of the time it uses javascript, and whether you're using javascript or not, there's no particular bit of code you can use for collapsible text with it guaranteed to work.
