A web page using the following two meta tags to allow fullscreen on iPad:
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black-translucent" />
The problem is now, that the status bar of the browser covers the header of the web page. How can this be avoided? The status bar is transparent, but that is not the solution, there are some links in the header of the web page, which can no longer be clicked.
