I see, thank you both for your response. I guess I will have to go with enclosing things in a Span or Div element.
If I’m designing my own writer though, I’m not sure why this:
[$x = 1+2$]{ .cs #math:equation caption=test}
Is any better than this:
[x = 1+2]{ .cs #math:equation caption=test}
Because in both cases I have access to the LaTeX math inside of the span. What added advantage does including the mathematical expression between dollar signs $...$ provide?
Regards,
Amine
For spans, it would rather be:
[$$x = 1+2$$]{ .cs #math:equation caption=test}
[$x = 1+2$]{ .cs #math:equation caption=test}
(Backticks are for code elements.)
