Try explicitly loading htmlize.el > (in the contrib/lisp directory of org) and then re-exporting ... You're spot on - importing htmlize.el did the trick. However, before importing it, there weren't any error messages about it being missing. All would work happily, but the source block didn't have the additional src and src-python tags. To me, this seems like a bug or at least not ideal, as the src tag and the src- tag are related to the HTML export of #+begin_src block, not on *how* the HTML is styled (i.e. by the user or htmlize). For those searching the mailing list later: ; For pretty-printed formatted source code on HTML export, ; load htmlize.el in init.el or the emacs config file (load-file "~/.emacs.d/orgmode/contrib/lisp/htmlize.el") I've got the orgmode source in the .emacs.d directory so I can pull updates using git, otherwise look for contrib/lisp/htmlize.el in the main Emacs directory. With htmlize.el loaded, exporting: ,============ | #+begin_src python :results output :exports both | print "Pi = ", 355/113.0 | #+end_src python `============ Results in the src block having the src and src-python CSS tags: ,============ |
|print
|"Pi =", 355/113.0

| | |
| Pi =  3.14159292035

`============ with an automatically added little "Python" flag box on the Python src block. Some custom CSS can be used to make the src and output a little more distinct. A simple way is it place these lines at the top of the file: #+style: #+style: However, you have to be consistent about using #+begin_src blocks rather than just a colon or using begin_example at the beginning of lines for src fragments that don't output anything, otherwise Python src they'll come out with the output colouring. The keyboard shortcut (< s tab) for getting a #+begin_src---#+end_src block is handy here. Although the example above relates to #+begin_src python blocks, the fix should work with other languages.
