Some time we have facing issue with multiple header in site
here I am showing you how you can create multiple header file in wordpress and you can add in different pages

• First copy header.php file
• After rename the copy file header-mynew.php
• You can replace mynew word with your header file name
• After open your template or php core file which you want to add header
• And change get_header(); to

get_header(‘mynew’)

if you want to add condition in page

<?php 
if(is_page(50)) {
 get_header('mynew');
}
else {
 get_header();
}
 wp_head();
?>

 Same you can create footer new file

I hope this article will be helpfull 🙂
