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
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: http://www.holithemes.com/ Description: A Twenty Seventeen child theme Author: Holithemes Author URI: http://www.holithemes.com Template: twentyseventeen Version: 1.0.0 */ @import url("../twentyseventeen/style.css");
To check the Child Theme
Appearance -> Themes
Now you will see WPB Child Theme. Click the “Activate” button to start using the child theme on your site.
