I am developing a Website with django. Now, let's say I have a database where values can change at any time. Every time the DB changes, I want to execute a function (no problem with that) and update some data I passed to a template without a page refresh.

At first, I thought about AJAX, but as it seems an AJAX-Request must be started from the frontend, right?

Long story short: What I want specifically is to update some CSS depending on some data changes in the backend without any page refresh.

Hope someone can help me
