Setup a child theme
Child Themes: Your New Best Friend
A child theme is a theme that inherits the functionality of another theme, called the parent theme. Child themes allows you to modify, or add to the functionality of that parent theme instead of modifying the core theme files directly. The problem with modifying core theme files is that your changes are in danger of being overwritten if and when you update the theme to the latest version down the road. This is obviously an undesirable outcome, especially if you've made dozens of adjustments throughout the theme. Ultimately, child themes are great for a few different reasons:
- If you modify an existing theme and it is updated, your changes will be lost. With a child theme, you can update the parent theme (which might be important for security or functionality) and still keep your changes.
- It can speed up development time.
- It’s a great way to get started if you are just learning WordPress theme development.
Setting up a child theme actually takes a little bit of work as you need to create a new directory for the child theme, specify the parent theme so WordPress knows where to apply the new changes, enqueue the parent theme's main CSS file, et cetera. You might also want to setup a functions.php file for various pieces of functionality that you want to add or modify. Fortunately, we've done all the heavy lifting for you in this area and all you need to do is use our provided child theme, which requires none of the setup listed above.
