So my wordpress theme is based on Sage theme by roots, I wanted to create a custom page (different header, footer etc..) from the current theme.
(So the basic idea behind this is to create a simple page which will act as a knowledge base page for our mobile app)
I achieved this by creating a custom template template-custom.php but how can I create a custom single page which inherits from the new template instead of Sage's base.php (As you may know this is Sage default wrapper)
