Specialized Page Template

Create a template for one Page: For more extensive changes, intended for just one specific Page, you can create a specialized template file, named with that Page’s slug or ID:

1. page-{slug}.php
2. page-{ID}.php

For example: Your About page has a slug of 'about' and an ID of 6. If your active Theme’s folder has a file named page-about.php or page-6.php, then WordPress will automatically find and use that file to render the About page.

To be used, specialized page templates must be in your active Theme’s folder:

/wp-content/themes/my-theme/

A specialized page template file can not be in a sub-folder, nor, if using a Child Theme, in its Parent Theme’s folder.
