What will this Django template render?
Given the base template and child template below, what will be the rendered output when the child template is used?
Django
{% raw %}
<!-- base.html -->
<html>
  <head><title>{% block title %}Base Title{% endblock %}</title></head>
  <body>
    <header>Header Content</header>
    <main>{% block content %}Base Content{% endblock %}</main>
    <footer>Footer Content</footer>
  </body>
</html>

<!-- child.html -->
{% extends "base.html" %}
{% block title %}Child Title{% endblock %}
{% block content %}Child Content{% endblock %}
{% endraw %}
A
&lt;html&gt;
  &lt;head&gt;&lt;title&gt;Base Title&lt;/title&gt;&lt;/head&gt;
  &lt;body&gt;
    &lt;header&gt;Header Content&lt;/header&gt;
    &lt;main&gt;Base Content&lt;/main&gt;
    &lt;footer&gt;Footer Content&lt;/footer&gt;
  &lt;/body&gt;
&lt;/html&gt;
B
&lt;html&gt;
  &lt;head&gt;&lt;title&gt;Child Title&lt;/title&gt;&lt;/head&gt;
  &lt;body&gt;
    &lt;header&gt;Child Content&lt;/header&gt;
    &lt;main&gt;Child Content&lt;/main&gt;
    &lt;footer&gt;Footer Content&lt;/footer&gt;
  &lt;/body&gt;
&lt;/html&gt;
C
&lt;html&gt;
  &lt;head&gt;&lt;title&gt;Child Title&lt;/title&gt;&lt;/head&gt;
  &lt;body&gt;
    &lt;header&gt;Header Content&lt;/header&gt;
    &lt;main&gt;Child Content&lt;/main&gt;
    &lt;footer&gt;Footer Content&lt;/footer&gt;
  &lt;/body&gt;
&lt;/html&gt;
D
&lt;html&gt;
  &lt;head&gt;&lt;title&gt;Base Title&lt;/title&gt;&lt;/head&gt;
  &lt;body&gt;
    &lt;header&gt;Child Content&lt;/header&gt;
    &lt;main&gt;Base Content&lt;/main&gt;
    &lt;footer&gt;Footer Content&lt;/footer&gt;
  &lt;/body&gt;
&lt;/html&gt;

What is the output of this nested block override?
Consider these templates. What will be the output inside the
tag when rendering 'grandchild.html'?
Django
{% raw %}
<!-- base.html -->
<html>
  <body>
    <main>{% block main_content %}Base Main{% endblock %}</main>
  </body>
</html>

<!-- child.html -->
{% extends "base.html" %}
{% block main_content %}Child Main{% endblock %}

<!-- grandchild.html -->
{% extends "child.html" %}
{% block main_content %}Grandchild Main{% endblock %}
{% endraw %}
A<main>Grandchild Main</main>
B<main>Base Main</main>
C<main>Child Main</main>
D<main>Child MainGrandchild Main</main>

Why does this template raise a TemplateSyntaxError?
This child template extends 'base.html' but raises a TemplateSyntaxError. What is the cause?
Django
{% raw %}
{% extends "base.html" %}
{% block title %}Child Title
{% block content %}Child Content{% endblock %}
{% endblock %}
{% endraw %}
AThe base template is missing the 'content' block definition.
BThe 'extends' tag must be the last tag in the template.
CThe 'content' block cannot be nested inside the 'title' block.
DThe 'title' block is not properly closed before starting the 'content' block.

How does Django resolve blocks in multiple inheritance?
Given three templates: base.html, intermediate.html (extends base), and final.html (extends intermediate). If all define a block named 'sidebar', which block content will Django render when rendering final.html?
AThe 'sidebar' block from final.html because it overrides all parent blocks.
BThe 'sidebar' block from intermediate.html because it is the immediate parent of final.html.
CThe 'sidebar' block from base.html because it is the original definition.
DA concatenation of all 'sidebar' blocks from base.html, intermediate.html, and final.html.
