Styling the

---

element

I have the following template in template/admin/change_form.html:

{% extends "admin/change_form.html" %}
{% block extrahead %}
  {% include "dojango/base.html" %}
  {% block dojango_content %}
  {% endblock %}
{% endblock %}

However for some reason it throws a

TemplatesyntaxError: TemplateSyntaxError at /admin/cms/post/add/
Caught RuntimeError while rendering: maximum recursion depth exceeded while calling a Python object
