It’s the same way as WordPress child theme. ( https://codex.wordpress.org/Child_Themes )
- Please create a folder by the name of the child theme you want, and then make a style.css within it.
Please input @import url(“../javo-directory/style.css”); withihn it.
- Please access your FTP and upload child theme in the wp-content / themes folder.
- Please move to Dashboard >> Appearance >> themes and check the creation of child theme.
- Please activate child theme.
- Please make the file you want to modify in our theme just as our theme path.
- When you modify a child theme file, it will be applied to your site.(A problem might occur if you customize it. We cannot help any personal customization.)
** MAKE SURE : If you change themes (even child theme or change theme name to your own), theme settings or widgets can be removed. you need to setup again. it’s a normal in wordpress when you change themes.
