Hi

You can’t delete Parent theme CSS. Why have you made this child theme if you are going to delete parent theme? The CSS you need to customization is only customize in child theme but not in the parent theme. You can customize in child theme css only.

Yes if you customize in parent theme then while updating our new version all your customization will be lost. So to be save from your customization we make child theme.

Thanks
Sunil
