org: Text areas in HTML export
12.6.9 Text areas in HTML export
--------------------------------
An alternative way to publish literal code examples in HTML is to use
text areas, where the example can even be edited before pasting it into
an application. It is triggered by ‘:textarea’ attribute at an
‘example’ or ‘src’ block.
You may also use ‘:height’ and ‘:width’ attributes to specify the
height and width of the text area, which default to the number of lines
in the example, and 80, respectively. For example
#+ATTR_HTML: :textarea t :width 40
#+BEGIN_EXAMPLE
(defun org-xor (a b)
"Exclusive or."
(if a (not b) b))
#+END_EXAMPLE
