When you first install your website on WordPress, you will be offered one of the default WordPress themes. If this does not meet your needs, you can install a new theme and customize it to your liking. But be careful: before proceeding with any customizations, you should immediately create a child theme.
The child theme is a sort of copy of the parent theme , which allows you hong kong phone number list to make all the changes you want to your theme and always keeps them saved, even when you make updates.
Why is it important to use a child theme?
Every time you customize your theme, the files that compose it are modified. If you modify an existing theme and then perform an update (which is important for security and to install new features released) all the changes made will be lost.
By using a child theme instead, you will have the clean and up-to-date parent theme on one side, and the child theme with your changes on the other.
In short, the child theme works together with the parent theme, integrating and complementing it: at the base you will have the updated parent theme, but above it there will be the child theme with your changes.
