CSS Update 3
Last night I noticed that while link-hovering worked on my Ubuntu laptop, nothing happened at all when I examined the site on my Windows desktop. Later, I asked a friend (using a Macbook) to test the links for me, who reported that the links shrank when hovered over. Today, my first priority was fixing this link-hovering issue in order to keep the site presentable. In the end, I decided to completely overhaul every link on the site, giving them a unified style that still highlights when hovered over, but without expanding or contracting.
I also added a footer, which for now is a mirror image of the navbar. In the future I may replace it with only a "back to top" button, but it's not a high priority. At this point, only the resume page would need such a thing anyway. Similar to this, in the future I may add a persistent navbar specifically for posts to allow readers to navigate to any post without having to return to the homepage.
The current site aesthetic is a bit skeletal, and I'm still not sure whether I like it or not. I'm partial to the unified link styling, so I'll most likely keep at least that much in future iterations.
