Serving content using ServeMux

A simple static file server would look like this:

package main

import (
    "net/http"
)

func main() {
    muxer := http.NewServeMux()
    fileServerCss := http.FileServer(http.Dir("src/css"))
    fileServerJs := http.FileServer(http.Dir("src/js"))
    fileServerHtml := http.FileServer(http.Dir("content"))
    muxer.Handle("/", fileServerHtml)
    muxer.Handle("/css", fileServerCss)
    muxer.Handle("/js", fileServerJs)
    http.ListenAndServe(":8080", muxer)
}

Found a mistake? Have a question or improvement idea? Let me know.
