Creating a WordPress child theme might sound complex, but changing a theme without losing your customizations when it updates is crucial. This beginner’s guide will walk you through what a child theme is, why you need one, and how to create one yourself using different methods. We’ll keep it simple so you can follow along even if you’re new to WordPress.

How Does a Child Theme Work, and Why Do You Need It?

A child theme in WordPress is like a layer added over the original theme (called the parent theme). It inherits all the styles and functions of the parent theme, which means it looks and behaves like the original but allows you to make changes without affecting the original files. This is great because you don’t lose customizations when the parent theme updates.

Why use a child theme?

  1. Safe Updates: Update the parent theme without losing your custom changes.
  2. Easy to Extend: Add new functionality without altering the core structure of the parent theme.
  3. Fallback Safe: The parent theme remains intact and functional if something goes wrong.

What to Do Before Creating a WordPress Child Theme

Before diving into creating a child theme, make sure to:

  • Backup Your Website: Always have a backup in case things don’t go as planned.
  • Check Theme Documentation: Some themes provide specific instructions or even a child theme that is ready to download and install.
  • Have Access to Your Site’s Files: You might need to access your website’s files through an FTP client or hosting file manager.

Method 1: Creating a Child WordPress Theme Manually

Step 1: Create a Child Theme Folder

  • Go to your website’s file directory, find wp-content/themes, and create a new folder for your child’s theme. Name it logically (like twentytwentytwo-child if modifying the Twenty Twenty-Two theme).

Step 2: Create a style.css File

  • Inside your child theme folder, create a file named ‘style.css.’ This will hold all your CSS customizations. Add the following information at the top of the file:


 Theme Name: Twenty Twenty-Two Child

 Theme URI:

 Description: My first child theme

 Author: Your Name

 Author URL:

 Template: twentytwentytwo

 Version: 1.0.0


  • Make sure to replace ‘Template: twentytwentytwo’ with the folder name of your parent theme.

Step 3: Enqueue Parent and Child Theme Stylesheets

  • Create a ‘functions.php’ file in your child theme directory. Add the following code to ensure your theme inherits the parent’s styles:

Php (copy the code below)


add_action( ‘wp_enqueue_scripts’, ‘my_child_theme_styles’ );

function my_child_theme_styles() {

    wp_enqueue_style( ‘parent-style’, get_template_directory_uri() . ‘/style.css’ );

    wp_enqueue_style( ‘child-style’, get_stylesheet_uri(), array( ‘parent-style’ ) );



Step 4: Activate Your Child Theme

  • Go to your WordPress dashboard, navigate to Appearance> Themes, and activate your new child theme.

Method 2: Creating a Child Theme With a Plugin for Classic Themes

Using a Plugin:

  • Install a plugin like “Child Theme Configurator” from the WordPress plugin directory.
  • Once activated, go to Tools > Child Themes and follow the plugin’s instructions to create a new child theme.

Method 3: Creating a Child Theme With a Plugin for Block Themes

Using a Plugin:

  • For block themes, use a plugin like “Create Block Theme.”
  • Navigate to Appearance> Create Block Theme. Select the parent theme and provide the details for your child theme, then click “Create.”

How to Add New Functionality to Your Child Theme

  • Modify Functions: Use the ‘functions.php’ file to add or modify PHP functions.
  • Add Custom Styles: Use the ‘style.css’ file to override parent theme styles or add new styles.

How to Troubleshoot Your WordPress Child Theme

  • Check Code Errors: Make sure there are no syntax errors in your ‘functions.php’ or ‘style.css’.
  • Consult the WordPress Codex: The Codex is an excellent resource for troubleshooting WordPress issues.
  • Deactivate Plugins: Sometimes, plugins can conflict with your theme. Try deactivating them to see if that solves the issue.

Bonus Tip: Find Out If Your Theme Has a Child Theme Generator

  • Check the Theme’s Documentation: Some theme developers offer a child theme generator tool on their websites, saving you time.


Creating a child theme may seem daunting initially, but it’s a powerful way to customize your WordPress site safely and effectively. Whether you make one manually or use a plugin, the effort can pay off by giving you a more personalized and resilient website. Remember to back up your site before you start, and take it one step at a time. 

FAQs About Creating a WordPress Child Theme

  • Can I use a child theme on any WordPress theme?

    Yes, you can create a child theme for any WordPress theme. This is a universal feature of WordPress designed to allow customizations without compromising the ability to update the parent theme safely. 

  • What if my child theme doesn't work as expected?

    First, double-check that you’ve followed all the steps correctly. Ensure that your style.css header is set up correctly and that you’ve enqueued the parent theme styles in your functions.php. If issues persist, try deactivating plugins to rule out conflicts, or check the WordPress forums for advice.  

  • Will using a child theme slow down my website?

    No, using a child theme won’t inherently slow down your website. It’s a safer way to make theme modifications without adding unnecessary bulk. However, the overall speed can be affected by the additional code and assets you add to your child theme.  

  • How do I update my child theme?

    Since you are the creator of the child theme, you will also make any updates to it. You need to manually adjust or improve the code in your child theme based on your needs or changes in WordPress core functionality. Keep track of changes you make to ensure compatibility with the parent theme updates.  

  • What should I do if the parent theme receives a significant update?

    After a major update to the parent theme, you should test your child’s theme on a staging site to ensure compatibility. Check if any functions or styles you have overridden are affected. Adjust your child theme’s code if necessary to maintain its functionality and Appearance.

  • Should I always create a child theme when using a WordPress theme?

    It’s recommended to create a child theme if you plan to make any modifications to the theme’s files. This way, you can ensure that your changes are preserved through theme updates. Creating a child theme might not be necessary if you only plan to make customizations using the WordPress customizer.
