There is real stuff between the comments and I found the code from that site. I have in in the function.php fine in the child theme directory. The php seems to be working now but the stylesheet doesn’t
require_once dirname( __FILE__ ) . ‘/plugins/myFile.php’;
function custom_style_sheet() {
wp_enqueue_style( ‘custom-styling’, get_stylesheet_directory_uri() . ‘/myStyle.css’ );
}
add_action(‘wp_enqueue_scripts’, ‘custom_style_sheet’);
