Child Theme Guide

Use a child theme to customize KnowX so your changes survive theme updates. Because KnowX is a classic PHP theme, standard WordPress child-theme conventions apply.

Create the child theme

1. In wp-content/themes/, create a folder, for example knowx-child.
2. Add a style.css with a header that names KnowX as the parent (the Template value must match KnowX’s folder name, knowx):

/*
Theme Name: KnowX Child
Template: knowx
Version: 1.0.0
*/

3. Add a functions.php that enqueues the parent and child styles:

<?php
add_action( 'wp_enqueue_scripts', function () {
    wp_enqueue_style( 'knowx-parent', get_template_directory_uri() . '/style.css' );
    wp_enqueue_style(
        'knowx-child',
        get_stylesheet_directory_uri() . '/style.css',
        array( 'knowx-parent' )
    );
} );

4. Activate KnowX Child under Appearance > Themes.

Override templates

Copy a template from the parent into your child theme with the same relative path, then edit the copy. WordPress uses the child version automatically. This works for root templates (single.php, page.php, archive.php, the page templates) and for files under template-parts/.

Keep the file’s docblock, including the Template Name: line for page templates, so the template stays selectable.

Prefer hooks and filters over template copies

Before copying a template, check whether a hook or filter does the job. KnowX exposes action hooks (knowx_before_content, knowx_after_content, knowx_sub_header, knowx_wp_body_open) and several filters for the footer, styles, fonts, and breadcrumbs. See Hooks Reference. Using hooks keeps your child theme smaller and more update-safe than duplicating markup.

Customizer and colors

Most visual customization (colors, typography, header, footer, layout) is available in the Customizer and does not require a child theme. Reach for a child theme when you need markup or logic changes, or CSS beyond what the Customizer and Additional CSS provide.

Note on the component system

KnowX’s PHP logic is organized as WP Rig components under inc/. These are internal to the parent theme. From a child theme, extend behavior through WordPress hooks and the KnowX filters rather than trying to re-register or replace parent components.
