In the documentation https://docs.djangoproject.com/en/dev/howto/static-files/
I read that static files should be put with their respective apps and called upon with
{% load staticfiles %}
<img src="{% static "articles/css/base.css" %}" alt="My image"/>
However later on in the docs it mentions that some static files don't pertain to a particular app. This is where STATICFILES_DIRS comes into play. If I read correctly STATICFILES_DIRS is a tuple for Django to use to look for other static files. I was wondering how would I call the static files that was called from the STATICFILES_DIRS?
ex: something like
<link rel="stylesheet" type="text/css" href="{% static "/css/default.css" %}">
Also I am not sure what to put for my STATIC_ROOT. Do I leave it empty? ('')
My proj tree
mysite
  \articles
       \static
       \articles
           \css
               base.css
  \static
       \images
       \css
           default.css
       \js 
  \templates
       base.html
  \settings.py 
This is currently in my settings.py regarding static files
# looks for static files in each app
STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
)
STATICFILES_STORAGE = (
    'django.contrib.staticfiles.storage.StaticFilesStorage'
)
# the absolute path to the directory where collectstatic will collect static files for deployment (OUTPUT)
STATIC_ROOT = ''
# This setting defines the additional locations the static files app will traverse if the FileSystemFinder finder is enabled.
STATICFILES_DIRS = (
    # used for static assets that aren't tied to a particular app
     os.path.join(BASE_DIR, 'static'),
)
# URL to use when referring to static files located in STATIC_ROOT
STATIC_URL = '/static/'
