ANSWER:

If you follow django’s guidelines, you can simplify your life greatly.

In your sample code, inside your application directory, create a folder called static. Inside this folder, place your css files.

Example:

$ django-admin.py startproject myproject
$ cd myproject
myproject$ python manage.py startapp myapp
myproject$ mkdir myapp/static
myproject$ cd myapp/static
myproject/myapp/static$ nano style.css

In your templates:

Make sure you add myapp to the INSTALLED_APPS list in settings.py. Now when you use the built-in development server, your style sheet will be rendered correctly.

Django searches for a static directory inside installed applications by default, and with current versions of django, static files are enabled by default.
