Re: [O] Orthogonality of blocks

[Christian Moe]

Oh, right, it gets a bit more complicated if you want better control 
of the tabulated blocks, i.e. border separation and spacing between 
the table cells. Then you first need to wrap them in a <div>. You 
could do that with literal HTML, or (my preference) with 
org-special-blocks. Use CSS to display the div as a table, and set 
border separation and spacing on it. Reworked example:

#+title: Side by side code blocks
#+style: <style>.parallel {display: table; border-collapse: separate; 
border-spacing: 2px 2px;}
#+style: pre.src {display: table-cell}</style>

How to say hello in two languages:

#+begin_parallel

#+name: Perl_hello
#+begin_src perl :results output
  # Perl
  sub say_hello {
      print "Hello, world";
  }

  say_hello;
#+end_src

#+name: Python_hello
#+begin_src python :results output
  # Python
  def say_hello():
      print("Hello, world")

  say_hello()
#+end_src

#+end_parallel
