If you want to make a personal website, you have two routes: Use a template thing like wordpress, with a GUI, or learn at least a bare minimum of HTML, CSS and probably some Javascript, as well as how to set up a server. What's offered in this article is not very useful to making a personal website... it's like if you wanted to bake a cake, and you read an article saying that frosting is made from sugar and butter. This isn't news and it's it's not particularly useful to baking your cake either.

Just to like, follow up: 99% of the point of making your personal website is, like, making it fucking personal which is to say that you put your own time and energy into learning something in the process. Copy/pasting random CSS from the web is not learning. Also, copy/pasting this particular CSS is not even showing the slightest bit of interest.

So consider: Why would anyone care about your personal website if you don't care enough to learn how to make it, you know, personal by actually learning a tiny bit about the art you're trying to put into practice?

And none of this even starts to explain why this junk would be popular here. There are some brilliant CSS hacks in the wild that deserve attention, but this is sub-par even for child's play that might teach you how to do something useful. It's not even a lesson. It's just some crap you don't understand that you might copy and paste, with almost no explanation.
