Box 1: App for SharePoint 2013
Box 2: Immersive Full Page
* Immersive (or full-page app): This shape provides a fully immersive experience by using the entire page. While this gives you complete control over the app experience, it is important to make sure that your app properly links back to the SharePoint site, so the user experience feels integrated and not lost. To make this simple, we provide a chrome control that not only lets your app automatically point a user back to their SharePoint environment, but it also provides your app with the current SharePoint cascading style sheet (CSS). So when SharePoint changes its CSS, say, through a theming change, your app will change its look and feel as well.
