Re: Footnotes on line and not raised

[Christian Moe]

Hi,

The footnote definitions are easy to fix with CSS since they are wrapped
in divs with the .footdef class.

#+begin_src css
  .footdef sup { vertical-align: baseline; font-size: 100%; }
#+end_src

But as you point out, the footnote references, are not as
straigthforward given the <sup><a class="footref"> structure -- at least
if you need other superscripts.

If you're not very concerned about cross-browser support, you can use
the :has() selector. Works fine in an up-to-date Firefox, but that's all
I'll promise.

#+begin_src css
  sup:has(.footref) { vertical-align: baseline; font-size: 100%; }
#+end_src

Otherwise, I think you'll need an export filter. Here's one that simply
sets the .footref class on the SUP element as well:

#+begin_src elisp
  (defun my-html-filter-footnotes (footnote backend info)
    "Export footnote references with a class definition on the SUP
  element to make them more amenable to CSS."
    (when (org-export-derived-backend-p backend 'html)
      (replace-regexp-in-string
       "<sup>" "<sup class=\"footref\">" footnote)))

  (add-to-list 'org-export-filter-footnote-reference-functions
               'my-html-filter-footnotes)
#+end_src

Now it's easy to style the footnote reference with

#+begin_src css
  sup.footref { vertical-align: baseline; font-size: 100%; }
#+end_src

One could perhaps make the case that Org ought to do this by default.

Yours,
Christian
