I am running through the flask tutorial and I can not seem to get the Template Inheritance to work. below are the examples of my code
My base.html is:
<!DOCTYPE html>
<html lang="en">
<head>
{% block head %}
<link rel="stylesheet" href="style.css" />
<title>{% block title %}{% endblock %} - My Webpage</title>
{% endblock %}
</head>
<body>
<div id="content">{% block content %}{% endblock %}</div>
<div id="footer">
{% block footer %}
© Copyright 2008 by <a href="http://domain.invalid/">you</a>.
{% endblock %}
</div>
</body>
</html>
my child Temp is:
{% extends "base.html" %}
{% block title %}Index{% endblock %}
{% block head %}
{{ super() }}
<style type="text/css">
.important { color: #336699; }
</style>
{% endblock %}
{% block content %}
<h1>Index</h1>
<p class="important">
Welcome to my awesome homepage.
</p>
{% endblock %}
my flask script is:
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def home():
return render_template("base.html")
if __name__ == "__main__":
app.debug = True
app.run()
Is there something specifically I should be doing regarding how I am incorporating the child template? Or should I be rendering the base template differently?

Template inheritance allows you to build a base “skeleton” template that contains all the common elements of your site and defines blocks that child templates can override.
html template file in a directory called templates inside your flask_app directory. Flask looks for templates in the templates directory, which is called templates , so the name is important. Make sure you're inside the flask_app directory and run the following command to create the templates directory: mkdir templates.
To use Template Inheritance we must first create a base template. A base template is just a simple skeleton that we will be used as a base for all other pages on our site. A base template defines areas where content can be inserted into. In Django, we define this area using the block tag.
Jinja extends works (superficially) like Python subclassing. You don't get an instance of a subclass when you instantiate a parent class, and you don't get the result of a child template when rendering the base template. Render the child template instead.
return render_template('child.html')
