Как мне заставить django находить css файлы?

Question

Я создаю свой первый проект Django, и я хотел создать страницу с картинкой в ​​качестве фона. Я следовал некоторым учебникам в Интернете, но затем, когда я запустил свой код, он показывает, что файл css не был найден.

Я уже пытался увидеть, был ли это путь к «статическому» файлу,и, возможно, это все еще есть, и я сделал это неправильно, но я не знаю, что еще делать.

Там это мои settings.py

будь как можно точнее, потому что я очень новичок в этом. Спасибо!
