Show demo od a CSS rule applied to real HTML element possible?

[jasondavis]

The demo I saw generated doc text.

Is it possible to also generate an HTML element and apply the style to it as a preview of the styles?

I wasn't able to tell if this does that or not. Some of the demo URLs are 404

It is supposed to do that, but the demo is broken. This project is unfortunately not actively maintained.
