Custom master
<!DOCTYPE html>
The master, we call it base.html, she defines a simple HTML skeleton may be two editions of the page layout. Submasters job is to fill their content block
Subtitled looks like
{% extends "base.html"%}
{% block title %}My amazing blog{% endblock %}
{% block content %}
{% for entry in blog_entries %}
{{ entry.title }}
{{ entry.body }}
{% endfor %}
{% endblock %}
extendsTag is the key here. It tells the template engine that this template "inherited" another template. When the system processes the stencil template, firstly, it will locate the parent template - in this case, is "base.html".
At that time, the template engine will notice base.htmlthe three blocklabels, and with the contents of the sub-template to replace the block.
