I have some questions about how to use ox-publish to create static sites.

I have followed steps documented at https://orgmode.org/worg/org-tutorials/org-publish-html-tutorial.html.

I have documented my steps and copied source and output at https://github.com/gptix/org-site-test

I have tried to search for answers on the emacs-orgmode mailing list, and on the web.

My three current issues:

- I do not understand how css info is being injected into output html files. I did not create any css file to be referenced, but styling is being included as CDATA.

- I do not understand what the
:auto-preamble t
in a component is for.

- I do not understand the relation between
(require 'ox-publish)
at the beginning of the tutorial, and
(require 'org-publish)
in the portion of the tutorial describing how to actually publish.

I'd love any help or a pointer to where I can read about these.

Thanks.
