In html/templates is there any way to have a constant header/footer across all pages?

Question

Reading the docs wasn't particularly helpful and I want to know if the structure

{{header}}

   {{content that always changes}}

{{footer}}

is achievable with golang.

Using text/template:

1. Code to render it to Stdout

   t := template.Must(template.ParseFiles("main.tmpl", "head.tmpl", "foot.tmpl"))
   t.Execute(os.Stdout, nil)
   

2. main.tmpl:

   {{template "header" .}}
   <p>main content</p>
   {{template "footer" .}}
   

3. foot.tmpl:

   {{define "footer"}}
   <footer>This is the foot</footer>
   {{end}}
   

4. head.tmpl:

   {{define "header"}}
   <header>This is the head</header>
   {{end}}
   

This will result in:

<header>This is the head</header>
<p>main content</p>
<footer>This is the foot</footer>

Using html/template will be extremely similar.
