How do I make a div full screen?

Question

I am using Flot to graph some of my data and I was thinking it would be great to make this graph appear fullscreen (occupy full space on the monitor) upon clicking on a butt

Answer 1

For fullscreen of browser rendering area there is a simple solution supported by all modern browsers.

div#placeholder {
    height: 100vh;
}

The only notable exception is the Android below 4.3 - but ofc only in the system browser/webview element (Chrome works ok).

For fullscreen of monitor please use HTML5 Fullscreen API
