Django base.html extended to homepage.html, static images appear, but home.css does not works

问题

Problem: As the title says I am building a django project the base.html extended to homepage.html and works fine, static images appear, but home.css does not works anywhere.

Update

I have switched in the base.html
from this <link rel="stylesheet" href="{% static 'css/home.css' %}">
to this <link href="css/home.css" rel="stylesheet" />
than I have also tried this: <link rel="stylesheet" type="text/css" href="{% static 'css/home.css' %}" />
It deletes a formatting on -s that was caused by another previously used .css that has been deleted since but the formatting sticked on. I have called this css property thickkk{color: red;} many places in both base.html and home.html and it still not working.
I have also get the following error message if I inspect the site with/F12/consol/ 127.0.0.1/:1 Refused to apply style from 'http://127.0.0.1:8000/css/home.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

Update ERROR message

Refused to apply style from 'http://127.0.0.1:8000/stacic/css/home.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

Properties: Python 3.7, Bootstrap 4

settings.py

STATICFILES_DIRS = [os.path.join(BASE_DIR, 'baseprojectfolder/static/')]

STATIC_ROOT = os.path.join(BASE_DIR, 'static')
STATIC_URL = '/static/'

base.html

I have created a base.html that hold the navbar and the footer.
This also has the CSS imported from a static css and also from bootstrap
It finds the static files because it imports the images that are appearing both here and in the home page

<!doctype html>
<html lang="en">
{% load static %}

home.html

I have used the center CSS property I have created

{% extends 'applicaonfolderofmine/templates/base.html' %}
{% load static %}

{% block content %}
<main>
<body>
  <div class="container">
    <h1 id="about" class="center" >About</h1>
...

home.css

it can be found in "django-project/certainapplication/static/css/home.css"

.center {
  margin: auto;
  width: 60%;
  padding: 10px;
}

I have read the following articles but they haven't answered my question:

css for base template in django
Adding css file after all extensions css files
Django UserProfile extension
Background from CSS not working in Base.html
Django mptt, extends "base.html"
{ % extends parent _ template|default:"base.html" % } vs {% extends "base.html" %} in Django?
Django templates extending and CSS
How does Django's extends work?

回答1:

As you have STATICFILES_DIRS remove STATIC_ROOT then type python manage.py collectstatic, then yes, then run your server again.

回答2:

The server should respond with the correct MIME Type for JSONP application/javascript and your request should tell jQuery you are loading JSONP dataType: 'jsonp'

Please see this answer for further details ! You can also have a look a this one as it explains why loading .js file with text/plain won't work. Disable Chrome strict MIME type checking
