模板未使用CSS

I'm using a template that links to a CSS file, and following some other posts on this board, I think I have everything correct, but the CSS is still not being applied. Also, when I use the Developer tools in Chrome is see the link to the CSS file as I put in in the template, and if I click on it, it takes me to the CSS file, which I assume shows me it can find the file.

Go code:

package main

import (
    "fmt"
    "strings"
    "os"
    "text/template"
    "net/http"
)

var tpl *template.Template

func init() {
    tpl = template.Must(template.ParseGlob("templates/*"))
}

func handler(w http.ResponseWriter, r *http.Request) {
    host, _ := os.Hostname()
    err := tpl.Execute(w, host)
    if err != nil {
        fmt.Println("Template Execute failed: ", err)
    }
}

func process(w http.ResponseWriter, r *http.Request) {
    r.ParseForm()
    fmt.Println(r.Form)
    fmt.Println("path", r.URL.Path)
    fmt.Println("scheme", r.URL.Scheme)
    fmt.Println(r.Form["url_long"])
    for k, v := range r.Form {
        fmt.Println("key:", k)
        fmt.Println("val:", strings.Join(v, ""))
    }
    fmt.Println(r.Form["wall"])
}

func main() {
    host, _ := os.Hostname()
    fmt.Println("host =", host)
    //err = tpl.Execute(f, host)

    swall := http.NewServeMux()
    //fs := http.FileServer(http.Dir("www"))
    //swall.Handle("/", fs)
    swall.Handle("/resources/", http.StripPrefix("/resources/", http.FileServer(http.Dir("resources"))))
    swall.HandleFunc("/", handler)
    swall.HandleFunc("/process", process)
    http.ListenAndServe(":8080", swall)
}

HTML:

<!doctype html>
<html>
<head>
    <title>Great Wall</title>
    <link href="/resources/css/gwall.css" type="text/css" />
</head>
<body>
    <main>
        <div id="page_title">
            <h1>Great Wall</h1>
        </div>
</main>
</body>
</html>

CSS:

h1 {
    color: red;
    font-size: 36pt;
    text-align: center;
} 

I tried everything I can think of and searched for several days, but I don't have much experience with templates and I'm at a complete loss right now. I know when someone tells me what I'm doing wrong I'll end up smacking myself on the forehead, but at this point I'll risk the bruising. Thanks for any help.
