Open webpage in fullscreen in Safari on iOS

Question

There is a fullscreen mode in Safari on iOS. Is it possible to activate this through javascript?

Answer 1

No, javascript cannot be used to switch between a fullscreen and normal mode in Safari on iOS.

The following meta tag must be included, and the page must be launched from a bookmark on the home screen, for it to operate in fullscreen mode:

<meta name="apple-mobile-web-app-capable" content="yes">

However, you can detect if the page is running in fullscreen mode or not with javascript using the read-only property:

window.navigator.standalone
