The background is light colored and the foreground is 100% black, and the text is full width and large on my phone. What would mobile support mean, a hamburger menu and no zooming? No thanks.

Luckily there's the reader mode. Those fonts are tiny and the background is too dark. But since there aren't any JS tricks this works very well. thumbs up.

Looks great for me on mobile. Maybe "supporting mobile" becomes more important when you do things that would otherwise make the mobile experience awful. Keeping it simple seems to support mobile automatically.

Looks fine in Chrome, but the text is tiny in Firefox. I think Firefox should handle this better.

Looks fine on mobile, header picture could be a bit thinner but other than that it's basically perfectly responsive.

I read the whole thing on a mobile and had no problem whatsoever.

I'm curious: what do you mean by "no support for mobile devices"? It loads on my phone and is readable; so you must mean something beyond that?

Sounds like modern day bootstrap websites.

Yeah, I can't believe they didn't use responsive CSS in 1999. Such ignorance.

That's because in 1999, HTML was considered responsive by default. It was up to the browser how to render it given its output medium.

AFAIK it was the iPhone's Safari that sucked first at rendering HTML without mobile-customized CSS.
