When it comes to WordPress theme development, one of the most effective ways to make customizations is by creating a child theme. In this article, we’ll explore the process of basic standard WordPress child theme development, its benefits, types, and frequently asked questions (FAQs) that will help you get started with child themes. Whether you’re a beginner or experienced developer, understanding child themes is essential for creating robust and upgradable WordPress websites.
What is a WordPress Child Theme?
A WordPress child theme is a theme that inherits its functionality from another theme, known as the parent theme. It allows you to customize the design and features of the parent theme without modifying the original code. This is particularly important as it ensures your customizations remain intact even after the parent theme is updated. A child theme consists of two primary components: a style.css file and a functions.php file, though it can also include template files if needed.
Why Use a WordPress Child Theme?
There are several reasons why you should consider using a child theme for your WordPress website:
1. Preserve Parent Theme Updates
By using a child theme, any changes made will be kept intact even when the parent theme is updated. This eliminates the risk of losing customizations when updates roll out.
2. Easier Troubleshooting
If an issue arises, you can easily switch to the parent theme without affecting the core functionality or appearance of your website. This makes debugging simpler.
3. Clean and Organized Code
Since child themes only include the necessary customizations, your code remains neat and manageable, which makes future edits easier.
4. Non-Destructive Customizations
Child themes allow you to modify elements like CSS, template files, and functions without directly editing the parent theme’s files, which keeps the process non-destructive.
Basic Steps for Creating a WordPress Child Theme
Creating a child theme is straightforward. Here’s a simple guide:
Step 1: Create a Child Theme Folder
Inside the wp-content/themes directory, create a new folder for your child theme. Name it something like your-theme-child to identify it easily.
Step 2: Add a style.css File
In the child theme folder, create a style.css file. This file should include basic information about the child theme, such as the theme name, description, version, and the parent theme it’s derived from. Here’s an example of the content:
/*
Theme Name: Your Theme Child
Theme URI: http://example.com/your-theme-child
Description: A child theme of Your Theme.
Author: Your Name
Author URI: http://example.com
Template: your-theme
Version: 1.0
*/
The Template field must match the folder name of the parent theme.
Step 3: Enqueue Stylesheets
In the child theme’s functions.php file, you need to enqueue the parent theme’s stylesheet. Add the following code to ensure the parent theme’s styles are properly inherited:
<?php
function my_theme_enqueue_styles() {
$parent_style = 'parent-style';
wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );
wp_enqueue_style( 'child-style', get_stylesheet_directory_uri() . '/style.css', array( $parent_style ), wp_get_theme()->get('Version') );
}
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
?>
This code tells WordPress to load the parent theme’s style first, followed by the child theme’s style.
Step 4: Customize the Child Theme
Now you can begin adding custom styles and modifications to your child theme’s style.css or functions.php file. You can also create custom template files to modify the layout and structure of your site.
Types of WordPress Child Themes
1. Simple Child Theme
A simple child theme inherits the parent theme’s styles and functionalities without any additional changes. It’s perfect for users who want to tweak minor aspects of the site, like CSS modifications or adding a few custom functions.
2. Advanced Child Theme
An advanced child theme extends the parent theme’s functionality with custom templates, functions, and styles. Developers may override parent theme template files like header.php, footer.php, or single.php to fully customize the site’s layout.
3. Plugin-Based Child Theme
A plugin-based child theme includes additional functionalities that are powered by plugins. For example, integrating page builders or advanced custom fields (ACF) into the child theme to add custom content management features.
Frequently Asked Questions (FAQs)
What is the difference between a parent theme and a child theme in WordPress?

While you don’t need to be an expert, having basic knowledge of CSS and PHP will help you customize a child theme more effectively. There are many tutorials and resources available to guide beginners through the process.
Can I use a child theme with any WordPress theme?
Yes, you can create a child theme for any WordPress theme, as long as the theme is designed to be extensible. Most modern themes, especially premium ones, are child theme-ready.
Is it safe to update the parent theme when using a child theme?
Yes, one of the main benefits of using a child theme is that any updates to the parent theme will not overwrite your customizations. Child themes are designed to ensure updates do not affect the changes you’ve made.
Can I add custom functionalities to a child theme?
Absolutely! Child themes are great for adding custom functions and features. You can extend the functionality of the parent theme by modifying the functions.php file in your child theme.
Conclusion
In conclusion, basic standard WordPress child theme development is an essential skill for anyone looking to make customizations to their WordPress website while maintaining the integrity and upgradability of the parent theme. By following the simple steps outlined above, you can create a child theme that allows for flexibility in design and functionality. Whether you’re making small tweaks or large-scale customizations, child themes provide a safe, non-destructive way to modify your WordPress site.
