(BTW For complete code files, you can also use the "include" directive
with the "code" option.

You can specify a custom html template to replace the default
docutils/writers/html4css1/template.txt
http://docutils.sourceforge.net/docs/user/config.html#template


Also, you can pass class arguments to (almost) any rST element using either
the "class" directive or (for directives) the "class" option::

  .. code-block:: xml
     :class: toggle-hide

So, maybe you don't need to wrap in a "container".

There is no such thing for rst2html5.py shipping with docutils.

There is indeed not rST for an HTML <input> element.
You could use raw HTML.

You would not only need a custom directive, but also an extension to the
HTML writer (unless you let the custom directive generate raw HTML).
