One of my subscribers asked to consider the question about creating child theme in WordPress on “your wish” page. In this lesson we’ll create child theme for e-commerce

The child theme is useful because any wordpress theme updates (or you need update it yourself). But if you have your custom theme settings, you will lose it after theme upadte. If you create child theme, you can override parent theme settings and don’t lose it while updating.
For creating child theme you need to create the folder with theme_name-child. Here you need to create style.css file, which you need to write standard wordpress theme comments, among which there is a Template: parent theme name. This string “makes” child theme to focus on its parent, while using its own settings if it has.
