I created emacs-reveal  for my own slides. Contents are centered vertically (default for reveal.js). CSS with “text-align: center” can be used for horizontal alignment. The howto for emacs-reveal is available at . First-level headings are centered vertically and horizontally. I just added slide 20 with horizontally centered text (underneath a heading, which—as ugly hack—could just be a non-breaking space I guess). I hope that helps and would be happy to help more. (Responses may be slow in the coming days, though.) Best wishes Jens  https://gitlab.com/oer/emacs-reveal  https://oer.gitlab.io/emacs-reveal-howto/howto.html
