If the code is like as follows, there is no drawing at all for the
second canvas. I just removed the first, and it shows:
Your browser does not support the HTML5 canvas tag.
=====================================================================================
<canvas id="canvas2" width="200" height="100" style="border:1px
solid #c3c3c3;">
Your browser does not support the HTML5 canvas tag.
</canvas>
<script>
var c = document.getElementById("canvas1");
var ctx = c.getContext("2d");
ctx.fillStyle = "#FF0000";
ctx.fillRect(0,0,200,100);
var c2 = document.getElementById("canvas2");
var ctx2 = c.getContext("2d");
ctx2.fillStyle = "#FFFF00";
ctx2.fillRect(0,0,200,100);
</script>
