What are the best practices for structuring and managing different header files for varying screen resolutions in a WordPress website?

When dealing with varying screen resolutions in a WordPress website, it is best practice to create multiple header files tailored for different screen sizes. This allows for a more responsive design and ensures that the website looks good on all devices. To manage these header files efficiently, you can use conditional statements in your theme's functions.php file to load the appropriate header file based on the screen resolution.

// functions.php

function load_custom_header() {
    if ( wp_is_mobile() ) {
        get_header( 'mobile' );
    } else {
        get_header();
    }
}
add_action( 'wp_head', 'load_custom_header' );
