Not sure why the search isn't working on that page. We'll have to check into it.
As far as the box (zenbox?) styling goes, we have built an Examples page into the templates themselves. On the main UNL site, it's located here: http://www.unl.edu/wdn/templates_3.0/examples/
, but if you're syncing the templates, you'll have the same page on your server as well.
In addition to the zenboxes, there's a bunch of other useful styling (and coding) examples on that page as well.
