Adding customizations to a parent theme
Lesson 3 Module 1
Many themes come with a child theme and a parent theme. The child theme takes the functionality of the parent theme and tweaks from the child theme. If you update the parent theme, you could be causing headaches for your site. Updates from the theme developer will generally overwrite any of your additions.
The safest way to update a theme is with a child theme. This allows you to make changes without ruining the original theme’s code and will ensure your changes are not lost.
