WordPress child themes are a great way to customize your website without altering the original theme. Child themes inherit all of the features and functionality from their parent, but can override any styling or functions with its own unique content.
This makes it so that you can create an unlimited number of customizations without having to modify anything on the base theme. In this article, we will explore what WordPress child themes are, how they work, and why they should be used in WordPress development environments.

What is a WordPress Child Theme?
A child theme is a WordPress theme that inherits the structure, HTML markup and styles of its parent. It allows you to modify or add new functionality without touching the original source code.
This is a simple and efficient way to customize your website without worrying about breaking the original theme. If you've ever updated or changed plugins, then you know how easy it can be for them to mess up your entire site. This can require hours of troubleshooting even though only one plugin was updated incorrectly. Using child themes not only helps prevent this from happening by keeping the original code intact, but it can also save your website if a plugin update goes wrong.
A child theme has complete control over its parent's files and allows you to modify or add new functionality without touching the original source code. You should use one for any customizations that are beyond what is built in to the WordPress core. This is especially important if your website is using a premium theme.
How to Create a WordPress Child Theme
Creating a child theme is easy, and it's the best way to customize any WordPress site.
The first thing you'll need to do is download an empty child theme that will inherit all of its styles from the original parent (this means no styling will be included). There are lots of great resources for finding quality child themes, but the one I typically recommend is Child Theme Configurator. It's a free plugin that allows you to choose between different parent themes and download their corresponding child themes with all necessary files including style.css, header.php, functions.php, and more.
Child Theme Configurator is a fast and easy to use utility that allows you to analyze any theme for common problems, create a child theme and customize it beyond the options of the Customizer. Designed for WordPress users who want to be able to customize child theme stylesheets directly, Child Theme Configurator lets you easily identify and override the exact CSS attributes you want to customize.
The Analyzer scans your rendered theme and automatically configures your child theme. It correctly enqueues theme and font stylesheets for optimum performance and handles vendor-specific syntax, giving you unlimited control over the Child Theme look and feel while leaving your Parent Theme untouched.
Child Theme Configurator parses and indexes your stylesheets so that every CSS media query, selector, property and value are at your fingertips. Second, it shows you how each customization you make will look before you commit it to the child theme. Finally, it saves your work so that you can customize styles in your child themes without the risk of losing your edits.
You can create any number of child themes from your existing Parent Themes. Child Theme Configurator lets you choose from your installed themes (even existing child themes) and save the results in your Themes directory.
Once you are ready, just activate the Child Theme and your WordPress site takes on the custom styles automatically.
What are the benefits of using WordPress Child Theme?
Using a child theme in WordPress has many advantages including better organization, easier updates, simplified migrations, and the ability to customize your main theme while keeping it safe from any conflicts or errors that could happen.
A WordPress child theme is just like a replica of its parent but with all code inside functions.php for customizations instead of everything being added directly to the primary theme. Modifying the parent theme directly can cause problems, especially during updates.
Child themes also provide developers with an easier way to test new changes without impacting the parent theme. It also keeps changes centralized to one place as opposed to scattering them throughout WordPress.
Frequently Asked Questions
What is the difference between WordPress theme and child theme?
A WordPress theme is the main design of your website, whereas a child theme refers to an individualized version that inherits all features and styles from its parent. You should use a child theme for any customizations that are beyond what is built in to WordPress core. This is especially important if your website uses a premium theme as it will be harder (or impossible) to make modifications without using child themes and proper coding practices.
What do you need to know about parent/child theme inheritance?
A few things to note about parent/child theme inheritance are that your child theme's files will all override the same ones in its parent. This means if you modify an existing file, it won't be changed by any future updates of the original theme or other themes using this one as a parent. Another thing worth mentioning is some features may not work properly until you add the code to your functions.php.
