It’s a safe approach to make changes to a WordPress theme without affecting the files of the parent theme. Any adjustments made in the child theme will be retained and continue to function even if the parent theme is updated.
Child themes are the most dependable and advised method of changing an existing theme because of this. You may easily overwrite the parent theme’s files with templates in the child theme instead of making changes directly to the parent theme’s code.
How to Create a Child Theme?
You must make a new folder for your custom theme in the theme’s directory in order to create a child theme. By providing a sample line in the commented code that indicates the theme name, you may identify the parent theme of the current child theme in the header code portion of the style.css file.
Beginner’s Note: Comments in CSS are often used to distinguish CSS in case there are IDs or classes with similar names for easier identification purposes. In this case, the comment is used to know which child theme’s CSS is being applied to which parent theme.
Any styles you define in your child theme’s style should be applied here because it comes after the parent theme’s style sheet.
Styles from the parent theme will be superseded by those from the CSS file. You must turn on the child theme in order to see the changes. All of the parent theme’s original attributes and features that the child theme did not change will be kept.
