I need to have more than one headers so this looks as a good idea but I'm not sure if it is valid. If so, what am I supposed to name a file? I named it head.php so far.
Example:
<html>
<!-- <head> tag -->
<?php get_template_part('head.php'); ?>
<body>
<header>
<nav> Navigation </nav>
<h1> Page title </h1>
