This is a valid Django template.

This template is valid as well, but it doesn't do what you think: it
extends the template that base.html evaluates to instead of extending
the template named "base.html".
To use the literal value "base.html", you need to put quotes around
the template name:
{% extends "base.html" %}

Aside from the typo ("extents" should be "extends"), this is fine.

In that case you'll need to make sure you're using either
layer_special or layer_specials as a block name. ;-)
