This may be stupid but I can't seem to get my canvas to fill the whole webpage. I create the canvas with
Code :
<body onload="webGLStart();">
 
	<script type="text/javascript">
		var X = document.body.clientWidth;
		var Y = document.body.clientHeight;
		document.write('<canvas id="test" style="border: none;" width="'+X+'" height="'+Y+'"></canvas>')
	</script>
 
</body>

but I always have scroll bars and the canvas doesn't start at the very top left. There is a little gap. Any ideas?
