如何正确配置Golang大猩猩/拍拍路由器以服务静态资产文件夹?

I have two html files that are parsed as follows:

var LoginTemplate = template.Must(template.ParseFiles(
    "views/_base.html",
    "views/login.html",
))

And executed as such:

func LoginFormHandler(w http.ResponseWriter, r *http.Request, ctx *models.Context) error {
    err := LoginTemplate.Execute(w, ctx)

    if err != nil {
        http.Error(w, err.Error(), 404)
    }
    return nil
}

Here are the contents of _base.html:

<!DOCTYPE html>
<html lang="en">

  <head>
      <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
      <!-- Meta, title, CSS, favicons, etc. -->
      <meta charset="utf-8">

      <title>{{ template "title" . }}</title>

      <meta http-equiv="X-UA-Compatible" content="IE=edge">
      <meta name="viewport" content="width=device-width, initial-scale=1">
      {{ template "styles" . }}
      {{ template "scripts" . }}
  </head>

  {{ template "content" . }}

</html>

The templates specified above are all defined in login.html. For example, "styles" wraps all of my CSS links, etc. In my main function, I use a gorilla/pat router to handle several page requests to the server. Additionally, I want to serve my static assets folders like this:

router.PathPrefix("/assets/").Handler(http.StripPrefix("/assets/", http.FileServer(http.Dir("./assets/"))))

  if err := http.ListenAndServe(":"+settings.Server.Port, router); err != nil {
        panic(err)
  } 

However, upon building and running my program, then navigating to local host, I see that none of the CSS or js appears to be rendering. My css and js folders are in this tree:

ROOT/

assets/

css/
js/
