I've tried different solutions already posted by users, but they didn't work for me.

**settings.py** of Project

```
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
DEBUG = False
ALLOWED_HOSTS = ["*"]

STATIC_URL = '/static/'
STATICFILES_DIRS=[

    os.path.join(BASE_DIR,'static')
]
STATIC_ROOT=os.path.join(BASE_DIR,'assets')

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

```

All my CSS files are in style folder inside the static folder.
And all images are in the media folder.

**Example of HTML file**

```
{% load static %}
<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <title></title>

    <link rel="stylesheet" href="{% static 'styles/LandingPage_CSS.css' %}">
</head>

   ...
      # IMAGES ARE LOADED LIKE THIS
     <img src="media/{{item.itemImage}}" alt="img" class=" card-img-top">

   ...

```

Also, I want to disable `DEBUG` because I want to make my custom 404 Error page.
404 page will also contain static Image and CSS, is it possible? Please help me with that too.
