Ok, so I must admit I’m a huge Apple nerd and at least try and watch the WWDC Keynote each year, or follow along on a liveblog (usually Engadget). When I found out recently that Webkit has support for dark mode, and that iOS is rumored to have a dark mode like macOS, I just had to make a dark mode theme for my site before WWDC this week.
On a mac, you should be able to switch between Light and Dark appearance on Safari, and have my site’s appearance switch back and forth accordingly.
