   Multiple Headers
   Different header for different pages.

   
   <?php
   if ( is_home() ) :
   	get_header( 'home' );
   elseif ( is_404() ) :
   	get_header( '404' );
   else :
   	get_header();
   endif;
   ?>
   

   The file names for the home and 404 headers should be header-home.php and header-404.php respectively.

Simple 404 page
The following code is a simple example of a template for an “HTTP 404: Not Found” error (which you could include in your theme as 404.php).

<?php get_header(); ?>

<h2><?php esc_html_e( 'Error 404 - Not Found', 'textdomain' ); ?></h2>

<?php get_sidebar(); ?>
<?php get_footer(); ?>
