/**
* This stylesheet will work pretty well with a regular Org Mode HTML export.
* However, you do have to turn off all of the defaults:
*
* (setq org-export-html-style-include-scripts nil
* org-export-html-style-include-default nil)
*
* and insert a call to the stylesheet:
*
* (setq org-export-html-style
