Is there a way to create a full-screen canvas in Chrome?

Looking to create a full-screen canvas in Google Chrome?

<style>
#canvas:-webkit-full-screen {
    height:100%;
    width: 100%;
}    
</style>
<button onclick="fullScreen()">Full Screen</button>
<canvas id="canvas"></canvas>
<script>
    function fullScreen() {
        var c = document.getElementById("canvas");
        c.webkitRequestFullScreen();
    }
</script>

This snippet of code achieves a full-screen effect for the canvas, but currently only sets the height of the canvas to be fullscreen.

Answer №1

To achieve a fixed position for the canvas element, try implementing the CSS rule fixed along with the following properties:

position:fixed;
left:0;
top:0;
width:100%;
height:100%;

In some cases, setting html and body with width/height: 100% may also be necessary.

To prevent zooming and ensure proper dimensions, consider directly setting the width and height of the canvas element using window.innerHeight and .innerWidth.
