<canvas style="z-index:0" /> <-- this will place the canvas behind all other elements document.body.style.background="url('"+document.getElementsByTagName("canvas")[0].toDataURL()+"');"; <-- convert canvas data to PNG and insert it.... <canvas id="canv" /><style> body{background:url(#canv);}</style>

Give your canvas an id, and then in CSS: * { margin: 0; padding: 0; box-sizing: border-box; } // basic reset body { width: 100vw; height: 100vh; } // 100% both x and y viewport #thisCanvas { width: 100%; height: 100%; } // or use inherit, to inherit from body

A way to do this (but i think it's not optimal) is to define you canvas in your body with an id selector for CSS and then define background in CSS. In HTML : <!DOCTYPE html> <html> <head> <title>Page Title</title> </head> <body> <div id="canvas"><canvas>Your Canvas</canvas></div> </body> </html> In CSS : #canvas { background:url(Your image URL) }
