[Answered ]-How to use triple nested quotes in django tempates?

It’s failing because you are using double quotes inside double quotes

Here is how it would look without the Django static files declaration

<div class="full-background" style="background-image: url('path/to/file')"></div>

Note the single quotes around the url path

If you want to use Django static files, just use single quotes outside and inside the static declaration

    <div 
       class="full-background" 
       style="background-image: url('{% static '/img/curved-images/white-curved.jpg' %}')"
    ></div>

Django will not see the outside single quotes when it looks for the static files.
