Re: Exporting LaTeX source blocks with HTML backend

[Ista Zahn <istazahn@gmail.com>]

Hi Xavier,

I think

#+begin_src latex :results drawer :exports results
  \begin{align*}
  x&=x\\
  y&=y
  \end{align*}
#+end_src

will give both syntax highlighting (in the code block) as well as
properly displayed equations in both latex and html export.

Best,
Ista
