Answer 1

Compare the paths to the style files in the page source code with the paths in the
upd browser console.
if in the console there is something like Resource interpreted as Stylesheet but transferred with MIME type application/x-css , then try adding it to setting.py

import mimetypes
mimetypes.add_type("text/css", ".css", True)
