Create a class that controls how each instance is drawn to the canvas. Check this code to see how. You use the loop and push new instances into an array.

Hi, you can define a class for add a style to a single canvas element and make a loop to create all of them. Run this code as example:
<!DOCTYPE html>
<html>
<body>
<style>
.canvas-example{
border: 1px solid red;
}
</style>
<script>
var c = document.createElement('canvas');
var target = document.body;
for(var i=0; i < 10; i++){
c = document.createElement('canvas');
c.setAttribute('id', 'Canvas'+i);
c.classList.add('canvas-example');
target.appendChild(c);
}
</script>
<!-- RETURN HTML IS
<canvas id="Canvas0" class="canvas-example"></canvas>
<canvas id="Canvas1" class="canvas-example"></canvas>
<canvas id="Canvas2" class="canvas-example"></canvas>
<canvas id="Canvas3" class="canvas-example"></canvas>
<canvas id="Canvas4" class="canvas-example"></canvas>
<canvas id="Canvas5" class="canvas-example"></canvas>
<canvas id="Canvas6" class="canvas-example"></canvas>
<canvas id="Canvas7" class="canvas-example"></canvas>
<canvas id="Canvas8" class="canvas-example"></canvas>
<canvas id="Canvas9" class="canvas-example"></canvas>
-->
