I was following along with this one, not really being a tutorial, but there are certainly things to learn in this video, anyway. I was doing this for fun on a HUGO website I'm playing with. And I pretty much cloned what Kevin did, but I can't get the browser to remember my prefers-color-sheme, no matter what I do it will always switch to dark, which I am using as the main theme for the site.
And I've checked all instances of it that I have set up with Hugo in css and golang html. I don't seem to have done anything different than Kevin. The only thing is that I'm on a pretty old 2013 Macbook Pro running OSX 10.14.6. On chrome and yes, everything on this system is themed dark. Google fonts does recognize my preference, so theirs kind of seems to work. Any clues/ ideas as to what might be causing this for me would be great.
