The Canvas appeared with HTML 5 and is now part of all modern browsers. A single line of HTML sets up a canvas, and you write to it from javascript. A style line can include CSS for the canvas, such as:
<canvas id="tutorial" width="150" height="150"> </canvas> <canvas id="tutorial" width="150" height="150" style="border:1px solid #000000;"> </canvas>This is pretty much the whole story from the HTML side of things, all the writing to the canvas is done from Javascript.
