Hello! Happy to see someone making use of our code. So you're aware, the navigation uses the checkbox trick to be hidden and revealed on mobile. It's a bit of a hacky workaround to avoid Javascript since we didn't want to use anything other than HTML and CSS when making this. Let us know if you want any coding help, and nice to meet you!
Added a term coined by a friend that we've sorely needed (ceter).
Also made minor tweaks to the About page and refined a few definitions.
