    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.

  2. 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(); ?>
