^^^^^^
This will handle requests for "/" to handleRoot, which is correct

^^^^^^^^^^^^^^^^^^^^^^^^
This will handle requests for /webpages/ to fs, stripping the prefix.
However, with the HTML file you have, the requests will be /css and
/js, not /webpages/css or /webpages/js
You could try this:
http.Handle("/css/",http.FileServer(http.Dir("webpages/css"))
http.Handle("/js/",http.FileServer(http.Dir("webpages/js"))
