There are a few solutions to your problem: a macro, a hook, a filter...

That's because `html' back-end never returns "^===$", but
"<code>=</code>", as "=" is a verbatim marker. Also, the output of
a filter function will appear in the final output. I doubt that you want
"~===~" to appear in your HTML document.
Here is one solution, with a filter:
#+begin_src emacs-lisp
(defun my-rule-markup (paragraph backend info)
(when (and (org-export-derived-backend-p backend 'html)
(string-match "<p>\n<code>=</code>\n</p>\n*" paragraph))
"<hr width=\"10%\"
style=\"width:10%;color:#000;background-color:#000;height:1px;border:none\"/>\n\n"))
(add-to-list 'org-export-filter-paragraph-functions 'my-rule-markup)
#+end_src
