How to Develop a Custom WordPress Twenty Twenty-Three Theme

Step 1: Create a Child Theme

To modify the Twenty Twenty-Three theme safely, create a child theme.

1. Create a new folder: twentytwentythree-child inside the wp-content/themes directory.
2. Create a style.css file:

/*
Theme Name: Twenty Twenty-Three Child
Template: twentytwentythree
*/

3. Create a functions.php file:

<?php
function enqueue_child_styles() {
    wp_enqueue_style('parent-style', get_template_directory_uri() . '/style.css');
}
add_action('wp_enqueue_scripts', 'enqueue_child_styles');
?>

4. Activate the child theme from the WordPress dashboard.

Step 2: Customize Templates

Use Full Site Editing (FSE) to modify templates and sections directly from the block editor.

• Navigate to Appearance > Editor.
• Select the template or template part you want to modify.
• Use the block editor to adjust layouts, colors, and content.

Step 3: Develop Custom Blocks

If you need additional functionality, create custom Gutenberg blocks using React.

Example of a simple block plugin:

<?php
function register_custom_block() {
    wp_register_script(
        'custom-block-js',
        get_template_directory_uri() . '/js/custom-block.js',
        array('wp-blocks', 'wp-editor')
    );
    register_block_type('custom/block', array(
        'editor_script' => 'custom-block-js',
    ));
}
add_action('init', 'register_custom_block');
?>

Step 4: Optimize Performance & SEO

• Use lightweight images and fonts for faster loading.
• Enable lazy loading for images.
• Add meta tags and structured data for better SEO rankings.

Step 5: Test & Deploy

• Test across multiple devices to ensure responsiveness.
• Use debugging tools like Query Monitor to check for errors.
