From [Django's official tutorial][1] (version 4.2):
> For the purposes of this tutorial, we’re using a file named > **background.png**, which will have the full path > **polls/static/polls/images/background.png**. > > Then, add a reference to your image in your stylesheet > (**polls/static/polls/style.css**):
```CSS body { background: white url("images/background.png") no-repeat; } ```
I'd guess that this is the currently preferred method, since they teach it that way.

I guess this is the preferred method, since they teach it that way. From the same tutorial, they say that the Jinja templating is not available in CSS files:
> The `{% static %}` template tag is not available for use in static files > which aren’t generated by Django, like your stylesheet.
