No parser, just a bunch of JavaScript functions that nest nicely, to create dense and readable DOM generation code.

As for Bepis, the mechanism by which elements nest seem complicated, as far as I understand it is controlled by sprinkling , and . throughout the string, I don't get why this would be necessary.
