Edit template files through a child theme. Editing Fitness Freak directly means losing your work the next time the theme updates.
Creating one
Create /wp-content/themes/fitness-freak-child/ containing a single style.css:
/*
Theme Name: Fitness Freak Child
Template: fitness-freak
Version: 1.0
*/
The Template: line must read exactly fitness-freak — that is what links the child to the parent.
Then add functions.php to load both stylesheets:
<?php
add_action( 'wp_enqueue_scripts', function () {
wp_enqueue_style( 'fitness-freak-parent', get_template_directory_uri() . '/style.css' );
wp_enqueue_style(
'fitness-freak-child',
get_stylesheet_uri(),
array( 'fitness-freak-parent' ),
wp_get_theme()->get( 'Version' )
);
} );
Activate the child under Appearance → Themes. Customizer settings are stored per theme, so you will need to set them again after switching.
Overriding a template
Copy the file from the parent into the child, keeping the same path — for example full-page.php — and edit the copy. WordPress uses the child’s version.
