Yes, I like it too. I tried to resize the browser window horizontally and the page neatly splits the content in multiple columns. Very nice.

It’s pure CSS columns, and not updated since 2012 or so.. yay for the web.

I’m surprised they’ve not caught on more, but it is quite hard to control where column breaks end up in a way that lends itself nicely to evenly lengthed columns and to keeping headings near the paragraphs they’re describing.
