How to Create a Child Theme in WordPress

By using a child theme the modifications will not be deleted if your parent theme gets updated.

Using a child theme can speed up development time, is the safest way and highly recommended.

Creating a Child Theme

First, open /wp-content/themes/ in your WordPress installation folder.

Select the parent theme for which you want to create a child theme.

Here I’m creating a child theme for “Twenty Seventeen”.

Create a new folder for your child theme, give any name and save it.

Open a text editor and paste this code:

Save this file as style.css in the child theme folder you just created.

/*
 Theme Name:   WPB Child Theme
 Theme URI:    https://holithemes.com/blog/
 Description:  A Twenty Seventeen child theme 
 Author:       Holithemes
 Author URI:   https://holithemes.com/blog
 Template:     twentyseventeen
 Version:      1.0.0
*/
 
@import url("../twentyseventeen/style.css");
