[racket] Racket Web App

I looked at the example posted in the documentation that goes something like this:

#lang racket

(require web-server/servlet
         web-server/servlet-env
         web-server/templates)

(define (start req)
 (response/xexpr
   `(html (head (title "Hello world!"))
          
          (body  "Hey out there!"))))


(serve/servlet start
               ;;#:port 80
               ;;#:listen-ip #f
               ;;#:servlet-path "/test"
               #:extra-files-paths
               (list 
			(build-path "C:/Users/howboutno5/Documents/Summer/test/htdocs/style.css")))

-------------------------------------------
However the style sheet does not appear to be loading at all.  The directory that the style sheet is in, is one below the location of the .rkt file if that makes any difference.

You should look at the #:extra-files-paths argument to serve/servlet
to specify where to find static files.

When I open the html file using a browser, it correctly displays the page based on the style sheet, but when I run my web app, it does not display things correctly.  Most specifically, it ignores the "background-image..." included in the style sheet.  I have included all the relevant code below.
