There are a few minor changes I would like to make to my attachment pages using CSS (such as image alignment etc) - I can't seem to figure out how to do this. I read on a website that I should be able to edit my single.php or image.php but when I open these files I don't really understand how to change them. I have a pretty decent understanding of CSS but I'm having trouble figuring out the php stuff. Can I just go and add CSS to these PHP files? When I look at them it's hard to imagine where I would even enter the css - can I just do it at the bottom or what?
I am also trying to replace the normal wordpress comments on my attachment pages with a FB comments app (using Facebook comments by Fat Panda) can anyone help me with that? Thanks!
