Custom Header Menu via link from existing header in Home Page.

Dear seniors,

I’ve been trying modify the WP header for a few days. So far, I have managed to change the header and background’s image and size. However, I find it a challenge to make it look like my Home page’s Header.

I wonder if it is possible to show my Header directly from my Home page through the code below? As it will be convenient when I add more Menu’s in my header in future.

The reason is because my Index page is a drag & drop builder. When my classified page is a full php builder. Now I’m setting up a Blog from WordPress. So with all 3 different site builders, it’ll be convenient to amend only 1 in future.

So maybe a simple code like this will workout on the header but I’m not sure where to add this code in WordPress.

Because I install WordPress through my site builder, VodaHost I’m not sure which code I should enter.

Option 1
<?php
include ‘header.html’;
?>

Option 2
<?php
include ‘https://www.mydomain.com/header.html&#8217;;
?>

Any comments or advise will be appreciated… Thank you so much in advance.. ??

Best Regards,
Foo
