How to Make a Child Theme in WordPress

Learning how to make a child theme in WordPress empowers digital agencies to customize their websites while ensuring future compatibility. WordPress, known for its robust platform, becomes a versatile tool when tailored to specific needs using child themes. These themes act as a powerful ally, enabling the full expression of brand identity while safeguarding customizations in the WordPress environment. But just learning isn’t enough, as we can say from our experience that hands-on practice is more important. And we have plenty of that, as White Label Agency has partnered with over 600 agencies and created over 10000 projects, bringing a wealth of expertise to the table.

Why Child Themes?

Before we begin, let’s explain the concept of a child theme: A child theme is a WordPress theme that inherits its functionality from another theme, known as the parent theme. It allows you to safely customize your website’s design and functionality without affecting the original theme, ensuring that your customizations are preserved even when the parent theme is updated.
Imagine building your dream website, tailoring every pixel to reflect your brand and vision. But then, a new update to your parent theme arrives, potentially overwriting your hard work. This is the nightmare scenario child themes prevent. They act as a protective layer, inheriting the functionality and styles of your chosen parent theme while allowing you to customize without fear of losing your changes.

But the benefits extend far beyond mere protection. Child themes grant you:

• Independence: Make unique changes to your website’s appearance and functionality without affecting the parent theme. Experiment with branding, layouts, and features without impacting other users who rely on the parent theme.
• Upgrade Flexibility: No more agonizing over theme updates. Child themes ensure your customizations remain intact even when upgrading the parent theme. This saves you time, resources, and potential headaches.
• Peace of Mind: Focus on your core business, knowing your website’s core functionality is secure and stable. Child themes act as a buffer, shielding your customizations from accidental or unwanted changes.

From Idea to Implementation: A Step-by-Step Guide

Ready to learn how to make a child theme in WordPress? Here’s a step-by-step guide:

Choose Your Parent Theme Wisely

Think of your parent theme as the foundation of your website. Choose one with features and functionality aligned with your needs, considering factors like:

• Compatibility: Ensure the theme is compatible with your WordPress version and plugins.
• Design Aesthetics: Select a theme that resonates with your brand identity and visual preferences.
• Future Updates: Choose a theme with a history of reliable updates and active community support.

Popular parent themes for agencies include Astra, OceanWP, and GeneratePress, offering a balance of features, flexibility, and ease of use.

Prepare Your Tools

Gather your essentials:

• Text Editor: Choose a code editor like VSC or Sublime Text for writing your theme files.
• Theme Files: Download the parent theme files for reference and extract certain elements for your child theme.

Create the Child Theme Folder

Open your preferred file manager and navigate to the wp-content/themes directory within your WordPress installation. Create a new folder and name it following the convention your-theme-child (replace “your-theme” with your chosen child theme name).

Build the Child Theme’s Stylesheet

This is the heart of your child theme, where you define its identity and override styles from the parent theme. Create a file named style.css inside your child theme folder and add the following code, replacing the placeholders with your information:

The @import line inherits styles from the parent theme, while the comment prompts you to add your custom styles below. Remember, start with specific styles to override elements you want to change, gradually building your child theme’s unique identity.

Enqueuing Styles and Scripts

WordPress automatically enqueues styles and scripts from your parent theme. However, you can selectively dequeue unnecessary ones and enqueue your own child theme styles using the wp_enqueue_style function in your functions.php file (we’ll create this file in the next step). This ensures efficient loading and avoids conflicts.

Customizing Functionality

While child themes primarily focus on visual customizations, you can also extend their power to modify functionality. Create a file named functions.php in your child theme folder and add the following code:

This code demonstrates how to enqueue a custom script and provides a starting point for adding further functionality. You can explore various techniques like:

• Overriding parent theme functions: Identify specific functions in the parent theme you want to modify and create your own versions with desired changes in the functions.php file.
• Hooking into parent theme actions and filters: These allow you to inject your custom code at specific points in the parent theme’s execution, enabling deeper customization without directly modifying its core files.
• Adding custom plugins: For complex functionality requiring more control, consider developing custom plugins within your child theme. This approach keeps your customizations modular and portable if you switch parent themes in the future.

When venturing into code customization, proceed with caution. Start with simple modifications and test thoroughly to avoid breaking your website. Even though learning how to make a child theme in WordPress is a captivating process, consider consulting a WordPress developer if you need help with complex functionality or feel unsure about coding changes.

Activating and Testing the Child Theme

Navigate to the “Appearance > Themes” section in your WordPress admin panel. Find your child theme and click the “Activate” button. Now, test your website thoroughly on a staging site or in a hidden section before pushing the changes live. Check for visual inconsistencies, functionality issues, and potential conflicts with plugins or other customizations.

Bonus Tips for Agencies: Unlocking Efficiency and Confidence

Easily track changes, maintain backups, and revert to previous versions with a click. Sleep easy knowing your website is always a stable, secure platform for your agency.
