What is a child theme?
A child theme in WordPress is a sub theme that inherits all the functionality, features, and style of its parent theme. Child themes are a safe way to modify a WordPress theme without actually making any changes to the parent theme’s files. If you are willing to go further with your theme customizations and include your own CSS, JavaScript, HTML and PHP code, the right way to do it, would be using a child theme. Here you can learn more.
We strongly recommend you to use one, otherwise you would lose your changes after a new theme update.
Download the child theme
You will find the child theme in the download bundle. Navigate to Envato Downloads Utillz All files & documentation. Unpack the ZIP file and extract only the file called Utillz-child.zip.
Install the child theme
WordPress considers a child theme as a separate theme. So installing the child theme works like installing the parent theme. Navigate to Appearance Add new Theme Upload, then browse the zip file previously download and extracted from Envato. Click Install Now and the theme will be uploaded.
