Finally getting around to fixing some bugs!!! No more weird underline in the footer on hover.
Sidenote, the Netlify CMS is amazing, and easy, and I didn't even know I had it installed so when I found it, it was a happy surprise. It just works.
It seems to only be set up for blog posts. I think that would work well for most people, especially since for SEO purposes, it's probably better that main pages like the homepage and about page keep the same content over time.
