Is there a way (CSS or javascript) so that a canvas area inside a website would become full-screen when the user double-taps it?

问题 I am just getting back into web design and a ton has changed. I'm going through lots of css tutorials at the moment, and I just read about position: fixed and its problems with mobile browsers.
