The Parent theme determines the look and function of the website, and using the WordPress software running at the bottom. In a sense, it is possible to think of the theme as an outfit. Website according to the chosen theme; it can seem serious, energetic, formal, childish, relaxed or fun.

WordPress Child Theme is a feature that uses the function and style features of another theme (its parent theme) installed on your system, but allows you to make changes on the style and functions of the theme without touching the files of the parent theme.

If we look at the basis of WordPress, the child theme is like normal themes. In the panel ″ Main Menu> Appearance> Themes ″ the child theme is listed along with other themes. You can select and activate like a normal theme.

The difference between them is that the child theme is directly linked to the main theme. If there is no main theme, the child theme cannot do anything and cannot be activated for use. This is because the child theme is not a standalone normal theme, either because the files of an already existing theme are changed or new files are added. It uses each feature in the parent theme and removes the desired features, changes or adds new features. Design (css), function (php), file structure etc… You can create a theme completely different from the main theme in terms of design and infrastructure, but if there is no main theme, there will be no child theme.

It is a good option when you’re customizing your WordPress theme. But sometimes it might be better option not to use a child theme. The parent theme of the website we use, may be suitable for our purpose and we may only want/need to make minor changes. In this case, it is better to use plugins instead of creating a child theme. Or you can add custom CSS to your WordPress site without editing any theme files.
