Is it possible to add a class to a paragraph in HTML export?

Is it possible to add a class to a paragraph in HTML export?

[Marcin Borkowski]

Hi,

I'd like to have a <p class="myfunnyclass"> in export.  I tried
#+ATTR_HTML :class myfunnyclass
but it didn't work.

Is there any way to do it?

TIA,

Wow, thanks a lot?  Any chance this will land in the "official"
Org-mode repo soon?

Best,

If deemed useful, I think this patch should use
`org-html--make-attribute-string' instead of hard-coding "class"
attribute:

  (attributes (org-html--make-attribute-string
               (org-export-read-attribute :attr_html paragraph)))

...

  (t (format "<p%s%s>\n%s</p>" attributes extra contents))

This way, attributes will not be limited to "class" only. See, for
example, `org-html-special-block'.
