I want to make a child theme for my wordpress site (Twenty-Fourteen theme fyi) so that my changes aren't overridden with every update. Apparently I need to create a new subfolder for the child theme in the wp-content/themes folder. Trouble is, I can't find it.
I've tried adding wp-content and wp-content/themes to the domain - it produced a blank white page. Tried searching for it (and just "wordpress") in the spotlight file search (yes I have a mac) and the only thing it came up with was some wordpress folders I installed back in 2010, which I don't even remember doing. Since I just recently set up this site in the past two weeks (May 2014) I'm pretty sure this is not what I'm looking for.
I should mention that I installed Wordpress via one of their sponsored web hosts, Dreamhost. This allowed me to bypass all those crazy setup steps and made the installation a lot easier. But now I have no idea where the files I need to access reside. I've heard people saying (and read here) that I should use an FTP client to access the underlying folders... I have no idea how to do this. That link also mentions "using the file manager provided in your host's control panel". Again, not sure what this is.
Can anybody help?
