12.6.8 Math formatting in HTML export
-------------------------------------
LaTeX math snippets (LaTeX fragments) can be displayed in two
different ways on HTML pages. The default is to use the MathJax system
(http://www.mathjax.org) which should work out of the box with Org mode
installation because <http://orgmode.org> serves ‘MathJax’ for Org mode
users for small applications and for testing purposes. If you plan to
use this regularly or on pages with significant page views, you should
install(1) MathJax on your own server in order to limit the load of our
server. To configure ‘MathJax’, use the variable
‘org-html-mathjax-options’ or insert something like the following into
the buffer:
#+HTML_MATHJAX: align:"left" mathml:t path:"/MathJax/MathJax.js"
See the docstring of the variable ‘org-html-mathjax-options’ for the
meaning of the parameters in this line.
If you prefer, you can also request that LaTeX fragments are
processed into small images that will be inserted into the browser page.
Before the availability of MathJax, this was the default method for Org
files. This method requires that the ‘dvipng’ program or ‘imagemagick’
suite is available on your system. You can still get this processing
with
#+OPTIONS: tex:dvipng
or:
#+OPTIONS: tex:imagemagick
