你如何链接到一个玉文件的CSS?

我目前正试图链接normalize.css但它不工作(使用套接字expression)

 html head title= "Real time web chat" link(href='/css/normalize.css') script(src='/chat.js') script(src='/socket.io/socket.io.js') script(src='http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js') body #content(style='width: 100%; height: 600px; margin: 0 0 20px 0; border: solid 1px #999; overflow-y: scroll;') .controls | Name: input#name(style='width:350px;') input#field(style='width:350px; display: inline; margin-left -90px;') input#send(type='button', value='send') 

你需要rel

 link(href='/css/normalize.css', rel='stylesheet')
