[Python] I can't load my CSS login page in Django admin

I have a Django project that I deployed without really adding any styling for 2 reasons:

1. 
   I didn't know any front-end back then.
   
   
2. 
   I wanted to do it for the sake of doing it.
   

Now, I have written HTML and CSS for the login page. The first place I want to apply it is the admin page, but this is what I see (as shown in the picture I shared). I can't find the problem in my project.

I also uploaded the project to GitHub here: https://github.com/manirng/sukablyat-django

Please ignore the name; I never thought it would go online.

i think my repo works(it should be on staticfiles,css,login.css and on login.html in the movies templates) now and these are the web page errors:
Refused to apply style from '<URL>' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

staticfiles/admin:
css:
login.css



the code i have in my login.html is:

{% load static %}
<link rel="stylesheet" href="{% static 'css/login.css' %}">
