Last year I created our new site with WordPress using the Graphene theme(which is awesome). Being a newbie to website development and wordpress in general I did not take the necessary time needed to learn about the benefits of child themes and just dove in making adjustments to the stylesheet. I am not very good with code, ftp and php confuses me, but I know how to search the internet to find what I need...except for this: Is it possible to create a child theme after I have modified the code in the stylesheet?
I don't know/remember what exactly I modified, only that I used the "Editor" under "Appearance" in the WordPress dashboard and modified parts of the stylesheet from there.
If I can't create a child theme without loosing my modifications is there something else i can do to help protect my site's security and functionality (my slider on my home page no longer works, it used to feature three pages)?
My website is http://www.nationalpondservice.com where I have Graphene v 1.6 installed
