ox-html: Allow "Figure %d:", etc. to be styled
* lisp/ox-html.el (org-html-paragraph): Wrap "Figure %d:" in
<span class="figure-number">.
(org-html-list-of-tables, org-html-table): Wrap "Table %d:" in
<span class="table-number">.
(org-html-list-of-listings): Wrap "Listing %d:" in
<span class="listing-number">.
* doc/org.text (CSS support): Mention .figure-number,
.listing-number, and .table-number.
I didn't change org-html-style-default, so these labels won't
appear special by default.
