I have an id of "one" on my page container. I'm first in the source order so I'm shown when the page loads.
This is a multi-page boilerplate template that you can copy to build your first jQuery Mobile page. This template contains multiple "page" containers inside, unlike a single page template that has just one page within it.
I have an id of "two" on my page container. I'm the second page container in this multi-page template.
Notice that the theme is different for this page because we've added a few data-theme swatch assigments here to show off how flexible it is. You can add any content or widget to these pages, but we're keeping these simple.
I have an id of "popup" on my page container and only look like a dialog because the link to me had a data-rel="dialog" attribute which gives me this inset look and a data-transition="pop" attribute to change the transition to pop. Without this, I'd be styled as a normal page.
