Nice site, I like the simplicity. One problem though, when I click on the "dark mode" switch, nothing happens.
By the way, I don't know about the others, but I would very much like to see a dark mode by default.
I don't know if OP saw your comment and fixed the problem but in case he did not, mine works perfectly. The problem might be with your browser or some extension in your browser. I am currently using Opera browser with no extensions.
