Very interesting project. I notice the site itself is written in Elm; it would be great if we could see the source code for the site, any chance of adding some of it to the examples section?
For instance, I am really unhappy with padding/margin, so that almost certainly come out. I have a nicer abstraction in mind that should solve HTML's problems with padding/margins/positioning. I can't say it will happen soon, but it's on the way.
P.S. If you want to look at other files, adding 'edit' to an Elm file gives you the source right now. http://elm-lang.org/edit/...
