This is one of the strangest ideas I've ever seen in a while. Nicholas Jitkoff has made a tool called itty.bitty that creates websites with all of the assets being contained within their own link. You can create a website without any HTML or CSS resources at all because it’s all been encoded into the URL itself.

For example: take a look at this humongous link:

And a clickable version If you like

This link contains all of the HTML and CSS to be contained in the site. It's an awesome idea, so why don't you make your own itty bitty site?
