Oakview: I tried what you suggested. I didn't really know what #branding was referring to until I acquainted myself with the Thematic page structure at http://bluemandala.com/thematic/thematic-structure.html
What you suggested does succeed in centering my header logo, but I'd like for the image to also be a clickable button that refers to a URL. With the way this is all laid out, I don't really know how to go about doing that.
There's also one problem with my revised code in that the area where my header logo used to be, referred to under #blog-title before, is a clickable button (even though it's invisible) in the way that I want the header image now referred to under #branding to work. Just need to switch it out somehow, I think.
For the record, my code so far:
