The latter. As I explained, ".org-center" is an internal style. > In fact, given that #+begin_center creates a .org-center div block, > that is centred by default CSS (and stylesheets of other formats), > I found your answer absolutely surprising. "Center" blocks are defined in the manual, along with their syntax. There is nothing surprising. Moreover, there is no such thing as a "Right" block. Or, more precisely, this falls into the special block category, which is handled differently in each export back-end. > I would be probably not alone on this feeling; see, for instance, > Fabrice Niessen’s Org mode syntax reference card [0], where (as far as > I got it) #+begin_right is presented as alignment tag for paragraphs > rather than tables: This reference card is not an official reference card. In any case, let me insist again on the following point: you can use "#+begin_right" in HTML to your heart's content if you define the appropriate CSS property.
