Frontend newbie here trying to get http://code.pb.io/jquery-snappish/ to work. I followed the instructions but the plugin doesn't seem to be working. When I turn it on it definitely responds because it messes with the layout, but I'm definitely missing something important and probably really stupid. Any help greatly appreciated!

Test on basic layout: http://johnnywang.nu/_TEST/snappish1/

I even tried copying the code source from his demo directly and it still doesn't work:  http://johnnywang.nu/_TEST/snappish2/

Let me know if there's anything other info I should put up.

Thanks!
