I'd like to make some change in the template; as some of them are made with plugins, one of them is directly change in the code (I just make the header transparent, as I would like to see the background image I use to replace main background color). But I'd like to know how I can make this change in order to get it even if I update the theme.
I try firt to copy the theme folder to make a change on a safe version of the theme, but it put my site down!!
How can I customise the theme for my convenience without loosing all my customisation at any update? Is it simply possible?
No link as I just test the theme offline on a mamp server, luckily, and just add the folder renamed on my hosted wordpress, and delete it as I see the mess in result.
