Non-destructive customisation of WordPress themes using a child theme
Similar to how Photoshop allows you to edit images using adjustment layers without altering the original image, you can use the same concept when customizing WordPress themes. Non-destructive customization has the advantage of being able to revert changes and keep the original files completely intact and untouched. [editor’s note: this is a very basic tutorial, but child theming is still not well practiced in my experience]
