Page templates
Now we can style and structure each page differently by using page templates. So for example, a CV page will have a different content structure to a product page.
The lines of code required for WordPress to recognize your file as a page template are:

<?php
/*
Template Name: Your Template Name
*/
?>
Always place this PHP piece of code on top of all your page templates. The given name appears in the Template dropdown in Edit Page in the Pages area.
