I understand how to call the style.css in my child theme
/*
Theme Name: suffusion-child
Description: Child theme for the suffusion theme
Author: Jamie Furlong
Template: suffusion
*/
@import url("../suffusion/style.css");
And I understand that my child theme functions.php is appended to the main functions.php file.
But how do I call the file 'post-header.php' which sits in a subfolder called 'custom' in my child-theme?
I have read this article and am unsure if I am supposed to add require_once( get_stylesheet_directory(). '/custom/post-header.php' ); to my child functions.php. I have tried this already but nothing has changed.
I know this is a simple problem, but what's the solution?
