CSS rules like
pre.src-awk:before { content: 'Awk'; }
in `org-html-style-default' don't work in the current Org version,
because the class attribute has been moved from the `pre' element to a
`code' child of that element. As a result, the name of the language
isn't dipslayed when hovering over a source block in the HTML file. I
am currently doing
(setq org-html-keep-old-src t)
but I think it's a kludge.
A better way out would be to move back the `class' attribute from the
`code' element to its `pre' parent in `org-src-html-block', or to change
the CSS selectors in `org-html-style-default'. This patch does the
former. (As for the latter, AFAIK there is no CSS selector which picks
precisely those `pre' elements that have `code' children with attributes
`src' and `src-LANG'.)
Cheers,
Raghu.
