Why doesn't Tornadoweb include styles?

Question

Tornado

There is a website - /var/www (example.com)
A tornadoweb server is running on port 8888

class Index(RequestHandler):
  def get(self):
    template=Loader("/var/www")
    self.write(template.load("index.html"))
    
application = Application([
  (r"/", Index),
])

When visiting example.com:8888, a purely HTML page opens, without styles. The site is opened from the same folder - locally and via port 80 styles are loaded, via 8888 and tornado - no.
What to do?
*import tornado.web, IOLoop, etc. written, just did not want to paste all the code here
