It's built using Meteor, and the page is constructed on the client. You can determine this by right-clicking the page, and selecting "View Source" in most browsers.
If you're having trouble with this, see this guide: http://webdesign.about.com/od/chrome/a/view-source-chrome.ht... as an example.
Once you see the HTML source, scroll to the area where the body tag is found. You'll notice the lack of any static content:
<body>
</body>
Or did you mean something else by static page?
