I want to change the font size in an existing post--a couple of titles. I did the css modifications for my blog five or six years ago and I remember how to recognize the way fonts are named and formatted, and the same for the font size and the colors and so forth. But I can't remember how I got into css for a given post. Do you go from the edit screen? When I click on Text (as opposed to Visual) I seem to be getting code but I don't think it's the css code. There's no fonts named, no font sizes.
Was that enough to explain it?
The blog I need help with is thewhitelilyblog.wordpress.com.
