How to Create a Child Theme

1. Create a Folder
In your WordPress directory, navigate to wp-content/themes and create a new folder for your child theme.

2. Add a style.css File

• Include the following header:

/*
Theme Name: My Child Theme
Template: parent-theme-folder-name
*/

3. Add a functions.php File

• Enqueue the parent theme styles:

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

4. Activate the Child Theme

• Go to Appearance > Themes and activate your child theme.

Common Customizations

• Modify templates like header.php or footer.php.
• Adjust styles in style.css.
• Add custom functions in functions.php.

Step 4: Add Custom CSS

For quick design changes, use custom CSS.

Where to Add Custom CSS

1. WordPress Customizer
   • Navigate to Appearance > Customize > Additional CSS.
2. Custom CSS Plugins
   • Use plugins like Simple Custom CSS or SiteOrigin CSS.

Step 5: Leverage Theme Options

Some themes come with built-in customization panels offering advanced settings.

   • Lightweight and highly customizable.
2. Divi
   • Includes a visual builder and extensive theme options.
3. OceanWP

Step 6: Use Hooks and Filters

Hooks and filters allow you to extend or modify your theme without editing core files.

Example: Add Content Before Posts

function add_custom_content_before_post() {
    echo '<p>This is custom content before the post.</p>';
}
add_action('the_content', 'add_custom_content_before_post');

Example: Modify the Excerpt Length

function custom_excerpt_length($length) {
    return 20;
}
add_filter('excerpt_length', 'custom_excerpt_length', 999);

Best Practices for Theme Customization

1. Backup Your Site
   • Use plugins like UpdraftPlus to back up your site before making changes.
2. Test on a Staging Site
   • Create a staging environment to test changes without affecting your live site.
3. Keep Accessibility in Mind
   • Ensure your customizations adhere to web accessibility standards.
4. Document Changes
   • Maintain a record of your modifications for future reference.
