For Django 2 2 up to 3  you have to load staticfiles in html template first before use static keyword    load staticfiles     lt link rel  quot stylesheet quot  href  quot    static  css bootstrap min css     quot  gt   For other versions use static    load static     lt link rel  quot stylesheet quot  href  quot    static  css bootstrap min css     quot  gt   Also you have to check that you defined STATIC URL in setting py At last  make sure the static files exist in the defined folder

I had the same problem  here s how I solved it   Following the first section of this very excellent Django tutorial  I did the following    Create a new Django app by executing  python manage py startapp new app Edit the settings py file  adding the following to the list of INSTALLED APPS   new app   Add a new module to the new app package named new app tags  In a Django HTML template  add the following to the top of the file  but after    extends  base template name html         load new app tags    In the new app tags module file  create a custom template tag  see below   In the same Django HTML template  from step 4 above  use your shiney new custom tag like so     multiply by two    5 0     Celebrate    Example from step 5 above   from django import template  register   template Library     register simple tag def multiply by two value       return float value    2 0

The app that contains the custom tags must be in INSTALLED APPS  So Are you sure that your directory is in INSTALLED APPS    From the documentation      The app that contains the custom tags must be in INSTALLED APPS in order for the    load    tag to work  This is a security feature  It allows you to host Python code for many template libraries on a single host machine without enabling access to all of them for every Django installation

You need to change      endblock content      to      endblock
