Thanks again for the responses. I've seen the links you both sent me, but again, they don't get specific enough to help me wade through this. I'm on the Fonts tab in the custom design section, and my kit ID is entered there, and my new typekit font family is listed there, but that's it... there doesn't seem to be anything else to do there or anything to control or change.
So I'm going to the CSS tab and trying to figure out if that's where I need to be. I tried entering this code from the Typekit Editor page:
... and then hit preview to see if I've done something, but get a new window that says "Failure" at the top and the only thing that appears in the window is a small line which reads "do you really want to do this?"
So the answer to that appears to be NO, I guess not.
I found this other post, again talking about the "selectors" which seems to be getting close to what I may need to be doing:
I've tried entering ".title" there and seem to have created a new "selector" so I then hit publish, but nothing happened with my blog. I resaved the kit ID, thinking that might help... no change. It seemed from the link above that I might need to create a "h1" or "h2" selector on the Typekit editor page, but for some reason those won't even create.
I'm thinking the answer must be in entering the right thing on the CSS tab page, but I don't know what that is. Again, all I'm trying to do is change the site title font, and its size and spacing, nothing else. No other changes anywhere.
Thanks again for your efforts to help me...this is so frustrating!
