+
+Step 6: The Templates
+=====================
+
+Now we should start working on the templates.  If we request the URLs now
+we would only get an exception that Flask cannot find the templates.  The
+templates are using `Jinja2`_ syntax and have autoescaping enabled by
+default.  This means that unless you mark a value in the code with
+:class:`~flask.Markup` or with the ``|safe`` filter in the template,
+Jinja2 will ensure that special characters such as ``<`` or ``>`` are
+escaped with their XML equivalents.
+
+We are also using template inheritance which makes it possible to reuse
+the layout of the website in all pages.
+
+Put the following templates into the `templates` folder:
+
+.. _Jinja2: http://jinja.pocoo.org/2/documentation/templates
+
+layout.html
+-----------
+
+This template contains the HTML skeleton, the header and a link to log in
+(or log out if the user was already logged in).  It also displays the
+flashed messages if there are any.  The ``{% block body %}`` block can be
+replaced by a block of the same name (``body``) in a child template.
+
+The :class:`~flask.session` dict is available in the template as well and
+you can use that to check if the user is logged in or not.  Note that in
+Jinja you can access missing attributes and items of objects / dicts which
+makes the following code work, even if there is no ``'logged_in'`` key in
+the session:
+
+.. sourcecode:: html+jinja
+
+    <!doctype html>
+    <title>Flaskr</title>
+    <link rel=stylesheet type=text/css href="{{ url_for('static', filename='style.css') }}">
+    <div class=page>
+      <h1>Flaskr</h1>
+      <div class=metanav>
+      {% if not session.logged_in %}
+        <a href="{{ url_for('login') }}">log in</a>
+      {% else %}
+        <a href="{{ url_for('logout') }}">log out</a>
+      {% endif %}
+      </div>
+      {% for message in get_flashed_messages() %}
+        <div class=flash>{{ message }}</div>
+      {% endfor %}
+      {% block body %}{% endblock %}
+    </div>
+
+show_entries.html
+-----------------
+
+This template extends the `layout.html` template from above to display the
+messages.  Note that the `for` loop iterates over the messages we passed
+in with the :func:`~flask.render_template` function.  We also tell the
+form to submit to your `add_entry` function and use `POST` as `HTTP`
+method:
+
+.. sourcecode:: html+jinja
+
+    {% extends "layout.html" %}
+    {% block body %}
+      {% if session.logged_in %}
+        <form action="{{ url_for('add_entry') }}" method=post class=add-entry>
+          <dl>
+            <dt>Title:
+            <dd><input type=text size=30 name=title>
+            <dt>Text:
+            <dd><textarea name=text rows=5 cols=40></textarea>
+            <dd><input type=submit value=Share>
+          </dl>
+        </form>
+      {% endif %}
+      <ul class=entries>
+      {% for entry in entries %}
+        <li><h2>{{ entry.title }}</h2>{{ entry.text|safe }}
+      {% else %}
+        <li><em>Unbelievable.  No entries here so far</em>
+      {% endfor %}
+      </ul>
+    {% endblock %}
+
+login.html
+----------
+
+Finally the login template which basically just displays a form to allow
+the user to login:
+
+.. sourcecode:: html+jinja
+
+    {% extends "layout.html" %}
+    {% block body %}
+      <h2>Login</h2>
+      {% if error %}<p class=error><strong>Error:</strong> {{ error }}{% endif %}
+      <form action="{{ url_for('login') }}" method=post>
+        <dl>
+          <dt>Username:
+          <dd><input type=text name=username>
+          <dt>Password:
+          <dd><input type=password name=password>
+          <dd><input type=submit value=Login>
+        </dl>
+      </form>
+    {% endblock %}
