Hi there, I chose the Graphine theme for my client's website a few months ago and she wanted it do to things that required custom CSS. In the mean time, a theme update has been released but before performing the update I read somewhere that theme updates would override my custom CSS, so I haven't updated it. What should I do? There were several things along the way that custom CSS solved, but I don't have a list of the changes I made (and don't remember). I read in the beginner's section of this forum something about creating child pages is recommended if you are going to use custom CSS, but I don't really understand what that means and didn't know to do that at the time I was making updates to her site.
What should I do? How do I handle theme updates without overriding our changes to CSS?
