It's html plus adhoc behavior description language. Behavior does not belong in HTML. You shouldn't have full programming language in HTML. And if you do, at least use existing language not make your own.
Since all of this is client side (and display: none; is the best you can do in terms of not revealing everything to the user anyways) you don't even need any behavior language in HTML. Just set classes to elements and manipulate them with the framework from outside.
