In WordPress, the header file is a PHP file that is typically included in the template files for a theme. The header file contains the HTML markup and other elements that appear at the top of every page on a WordPress site, such as the site title, navigation menu, logo, and search bar.
The header file is an important part of a WordPress theme, as it helps to establish the overall look and feel of the site and provides users with a consistent visual experience as they navigate through different pages.
Here is an example of a simple header file in WordPress:
phpCopy code<!DOCTYPE html>
<html <?php language_attributes(); ?>>
<head>
<meta charset="<?php bloginfo('charset'); ?>">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title><?php wp_title('|', true, 'right'); ?><?php bloginfo('name'); ?></title>
<?php wp_head(); ?>
</head>
<body <?php body_class(); ?>>
<header>
<div class="site-branding">
<?php if (has_custom_logo()) {
the_custom_logo();
} else { ?>
<h1 class="site-title"><a href="<?php echo esc_url(home_url('/')); ?>" rel="home"><?php bloginfo('name'); ?></a></h1>
<?php } ?>
</div>
<nav class="main-navigation">
<?php wp_nav_menu(array('theme_location' => 'primary', 'menu_id' => 'primary-menu')); ?>
</nav>
</header>
