org-html-htmlize-generate-css
org-html-htmlize-generate-css is an interactive autoloaded Lisp function in `ox-html.el
'.
(org-html-htmlize-generate-css)
Create the CSS for all font definitions in the current Emacs session.
Use this to create face definitions in your CSS style file that can then
be used by code snippets transformed by htmlize.
This command just produces a buffer that contains class definitions for all
faces used in the current Emacs session. You can copy and paste the ones you
need into your CSS file.
If you then set `org-html-htmlize-output-type' to `css', calls
to the function `org-html-htmlize-region-for-paste' will
produce code that uses these same face definitions.
