Because it's document.getElementById but you wrote Document.getElementByid which is incorrect.
//check below it's correct
var canvas=document.getElementById("canvas1");

did you remove the dots & write document.getElementById correctly?
The below code is working fine. if the below doesn't work then it may be your browser or device.
<html>
<body>
<canvas id="canvas1" width="400" height="300"></canvas>
<script>
var canvas=document.getElementById("canvas1");
var ctx=canvas.getContext("2d");
ctx.fillStyle = "#FF0000";
ctx.fillRect(10,10, 100, 100); // ctx.fillrect(x,y,width,height)
ctx.rotate( (Math.PI / 180) * 25); //rotate 25 degrees.
ctx.fillStyle = "#0000FF";
ctx.fillRect(10,10, 100, 100);
</script>
</body>

There was a typo in fillStyle the S should be capital in it. check the demo it shows colors now.
