The main idea here is to show how one can create a new template instead of trying to customize the existing page. There are 2 ways to integrate them both,
1. Insert a small code snippet and rename HTML to PHP
2. Configure web server to process HTML as an active script
The article focuses on #1 as not many will have absolute control over the web server configuration.
Nonetheless, I suppose “How to create new template” could have been a more appropriate title. Thx for the feedback.
