What is a WordPress Child Theme
One of the first tasks when setting up a new WordPress website before even getting to the question of What is a WordPress Child Theme is to choose a main theme, this may be anything from an exciting or dreaded job depending upon your own experiences. As far as I was concerned for many years it went between being a necessary evil at best to a job I hated at worst.
I was never comfortable with the route that so many people seem to take, i.e. Theme Forest, even in my early days with little WordPress experience I just didn’t trust them and that was often borne out with bad experiences further down the line when it came to managing and updating themes. Which brings us to the subject of Child Themes, child themes were introduced by the WordPress community (WordPress is open source and developed with input from the community).
In the early days before Child Themes an update to your WordPress theme would result in you losing any custom styling and changes that you had made to the theme.
This could create serious stress when, in the event of an exploit the theme provider might inform you of an update and that you need to update your own theme ASAP. What to do? Loose all of your custom styles if you update or run the risk of your site getting hacked if you don’t?
What is a WordPress Child Theme in Relation to the Parent Theme?
The WordPress community of developers introduced a solution – the concept of parent theme and child theme was borne. The child theme in WordPress inherits all of the functionality, features and code of the parent theme without touching the parent theme at all. Now, with a child theme installed and activated you could change the styling of the parent theme while still being able to update the parent theme.
What is a WordPress Child Theme – The Answer from WordPress
As with most WordPress questions the answer can be found on the Codex:

- Using a child theme can speed up development time.
- Using a child theme is a great way to learn about WordPress theme development.
As great a move as this was the majority of WordPress websites still didn’t (and don’t) take make use of the advantages to be gained. Why not? Mostly one suspects through the ignorance of just not being aware or otherwise a head in the sand approach as a result of the fear of all things technical.
For all that the process of creating a Child Theme is relatively straightforward.
Creating a WordPress Child Theme
This a a basic walk through of creating a child theme. Firstly create a new folder for your child theme, name it something like /wpstream-child/ Within your new theme folder, create a file called style.css and add the information as below. The theme Name, URI, Description and Author are your choice.
Theme Name: WPStream Child Theme
Theme URI: https://www.i-netco.co.uk/wpstream/
Description: WP Stream Child Theme
Author URI: https://www.i-netco.co.uk
/* =Theme customization starts here
The “Template:” and @import sections are important here as they identify the parent theme that imports the CSS from the parent or orginal. You must make sure the path to your parent theme’s css file is correct, and that the “Template:” parameter correctly identifies the name of the parent theme and in the correct case. The folder of our parent theme is “WPStream” and the @import URL reflects this.
How to Activate a WordPress Child Theme
