Apparently css can't be read.
I checked settings.py to find out the cause.
settings.py
# snip
DEBUG = False
ALLOWED_HOSTS = ['localhost','0.0.0.0']
# snip
The above DEBUG = False was suspicious, so if you set it to True, css can be read.
DEBUG = False is supposed to be a production environment, and it seems that static files are read from a web server such as nginx.
counter-measure
In order for css to be loaded, it is necessary to support ** either ** of the following two.
1. Set DEBUG = True in settings.py
If set to True, css in the project will also be loaded.
2. Use the python manage.py runserver --insecure command
With the --insecure option, the css in your project will be loaded.
bonus
settings.py
DEBUG = False
ALLOWED_HOSTS = ['*']
Css was not applied with this setting. It seems that css cannot be read just by setting ALLOWED_HOSTS arbitrarily.
