如何在elm中使用单独的CSS文件？

.container {
  background-color: #f2f2f2;
  padding: 20px;
}

.title {
  font-size: 24px;
  color: #333;
}

module Styles exposing (..)

import Css exposing (..)
import Css.Global as Global


stylesheet : Stylesheet
stylesheet =
    let
        container =
            style
                [ backgroundColor (rgb 242 242 242)
                , padding (px 20)
                ]

        title =
            style
                [ fontSize (px 24)
                , color (rgb 51 51 51)
                ]
    in
    Css.stylesheet
        [ Global.fromFile "styles.css"
        , container
        , title
        ]

import Html exposing (div, text)
import Styles exposing (..)

view : Html msg
view =
    div [ style stylesheet.container ]
        [ div [ style stylesheet.title ] [ text "Hello, Elm!" ]
        ]
