In this article, we will discuss “Child Theme Importance in WordPress”. First, we need to know, what is a Child theme? A child theme is a theme that inherits the functionality and styling of another theme, called the parent theme. A child theme is used to modify existing themes while still maintaining their design and code. Mostly, child themes used when we want to customize the existing theme without losing the ability to upgrade the theme.

Basically, the child theme inherits the code, functionality, and design of the parent theme. We can customize the theme as per requirements. All your customization placed in the child theme directory, so no worries about the parent theme upgrades.

I recommend child theme implementation only if you want to apply any kind of customization. This will reduce your headache, to differentiate your customization from your parent theme.

Advantages of WordPress Child Theme

  1. Keep original theme safe: Using the child theme, our parent theme is safe and untouched. This means we can reinstall it any time if any case of damage
  2. Faster development: Child theme provides a platform to make development faster. No need to write code from scratch, this will make our development cost-effective and faster.
  3. Easy to customize: We can easily apply customization for the parent theme, as per the available hooks and filter of the parent theme.

Disadvantages of WordPress Child Theme

  1. Required knowledge of parent theme: Using of child theme requires proper knowledge of parent theme and its functionality. Not all the developers are the same, which means you have to know the theme and its file behavior.
  2. The parent theme is Abandoned: Sometimes theme-creators abandon the projects due to the theme sales. This means no longer receive any update for your theme. So do proper research to pick up a good parent theme. Also, you can check the review of existing users before buying any theme.
