Yeah, you're right, the body tag is the next best thing, and is probably more common. I should have mentioned that as a possible solution. Hi Robert, thanks for the comment.

I do this all the time. For example, by dynamically changing the class on the body tag I can change the look and feel of a page: body.red h1 { color: red; } body.red p { font-size: 14pt; } body.green h1 {color: green; } body.green p {font-size: 12pt; font-weight: bold; } Instead of attaching an id or class on the html tag, attach them on the body tag.

After tearing a part & snooping through the User Guide I found that what's most interesting is that Apple uses DATA URIs for lots of images (including inside that JSON fil). That drastically reduces the number of HTTP requests; great for WiFi. But even cooler, all that JSON is loaded into a browser-based SQLlite Db via JavaScript. Between using a local Db in the browser and HTML5 Page Caching it's no wonder that the web app feels very fast on revisiting the UI. Paul David –
