Why use a Child theme?
Safe Updates. You can easily modify your website using child themes without ever changing the parent theme. When a new version of the parent theme appears, you can safely update it as all your modifications are saved in the child theme.
Easy to Extend. A child theme has a great flexibility. It does not require writing a lot of code. You can modify only those template files and functions that you need.
Note : When you install one of our themes you must upload both parent and child theme folders to wp-content / themes but you should only activate the Child theme via Dashboard -> Dashboard -> Themes.
Modifying files from the Parent theme folder
While you should never edit files in your Parent theme, if you really must, the safest way to do it is to download a copy of the file you want to modify on your computer, make the changes, and then upload it into your child theme folder.
Note : This way of modifying the files can be used for any files from the parent theme — note that you must re-create the same folder structure in your child theme that exist in the parent theme in order for the modifications to take effect.
