Hiding the Safari UI Components
Set the meta-tag compatible with the Apple-mobile-web-web application to yes to enable stand-alone mode. For example, the following HTML displays web content using standalone mode.
<meta name="apple-mobile-web-app-capable" content="yes">
Changing the appearance of the status bar
You can change the appearance of the default status bar to black or black-translucent. With black-translucent, the status bar floats above the contents of the full screen, instead of pressing it. This gives the layout greater height, but obstructs the top. Here is the required code:
<meta name="apple-mobile-web-app-status-bar-style" content="black">
For more information about the appearance of the status bar, see apple-mobile-web-app-status-bar-style.
For example:
