css not working in django?

Question

Django

I work with django 2 but style.css doesn't work completely. (like part of the code works and the other does not). If the css code is inserted into the html file, then all the code will work correctly.
Here is how I included css and settings file

<link rel="stylesheet" type="text/css" href="{% static 'main.css' %}">

STATIC_URL = '/static/'

MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'

CRISPY_TEMPLATE_PACK = 'bootstrap4'
