Creating Your Child Theme: Step by Step

Follow these steps to create your own child theme in WordPress:

1. Choose a Parent Theme:

A parent theme is a complete WordPress theme. Meaning, it includes the WordPress template files and assets required for the theme to work. Only index.php and style.css, the main template and style files, are necessary for creating WordPress templates.

Select the parent theme you want to build your child theme. You can find thousands of free and premium themes in the WordPress Theme Directory or from third party sources.

2. Create a New Directory:

Inside your WordPress installation, navigate to the wp-content/themes/ directory. Create a new directory for your child theme. It’s recommended to name it something like parent-theme-name-child to keep it organized.

3.Create a Stylesheet (style.css):

Inside your child theme directory, create a style.css file. This file serves as the starting point for your child theme. Add the following code at the top of the style.css file:

Make sure to replace “My Child Theme,” “Parent Theme Name,” and “parent-theme-directory-name” with your theme’s information.

4. Enqueue the Parent Theme Stylesheet:

To inherit styles from the parent theme, open your child theme’s functions.php file (create one if it doesn’t exist) and add the following code:

This code enqueues the parent theme’s stylesheet.

5. Activate Your Child Theme:

Log in to your WordPress dashboard, go to “Appearance” > “Themes,” and activate your child theme. Your website will now use the child theme while inheriting the functionality and styles of the parent theme.

Customize Your Child Theme:

You can now start customizing your child theme. You can add custom CSS to the style.css file or override specific template files by copying them from the parent theme directory to your child theme directory.
