Hi,
The docstring for org-html-head gives this example:
#+BEGIN_SRC html
<style type="text/css">
<![CDATA[
.timestamp, .timestamp-kwd { color: #268bd2 !important; }
blockquote > p { color: #333333 !important; font-size: 95% !important; }
]]>
</style>
#+END_SRC
When I customized the variable, I used those "CDATA" lines exactly, but
they prevented the stylesheet I added from working in the browser
(Chrome in this case). When I changed the "CDATA" lines to the ones
that are in org-html-style-default, it worked:
#+BEGIN_SRC html
<style type="text/css">
<!--/*--><![CDATA[/*><!--*/
.timestamp, .timestamp-kwd { color: #268bd2 !important; }
blockquote > p { color: #333333 !important; font-size: 95% !important; }
/*]]>*/-->
</style>
#+END_SRC
So I'm guessing that the docs need to be updated.
Thanks.
