Set the apple-mobile-web-app-capable meta tag to yes to turn on standalone mode. For example, the following HTML displays web content using standalone mode.
<meta name="apple-mobile-web-app-capable" content="yes">

You can change the appearance of the default status bar to either black or black-translucent. With black-translucent, the status bar floats on top of the full screen content, rather than pushing it down. This gives the layout more height, but obstructs the top. Here’s the code required:
<meta name="apple-mobile-web-app-status-bar-style" content="black">
For more on status bar appearance, see apple-mobile-web-app-status-bar-style.
