While futzing around with either my style.css file or footer.php, I managed to accidentally set the font size of my footer navigation (prev, next, etc links) to something absurdly large, and I can’t remember how I did it. I’m futzing around more to try and remember how I did it, so I can reset it to something a little more normal, but I’ve totally forgotten what I did to reset it to begin with.
I think it may have happened while I was trying to set the footer type — RSS feeds, copyright notice, all that stuff — to something larger than teensy-weensy and, seeing no change, moved on, not realizing the huge mistake I’d made that didn’t show up until I’d added several pages worth of content.
