Definition and Usage

Differences Between HTML 4.01 and HTML 5
The <canvas> tag is new in HTML 5
Tips and Notes
Tip: You can write text between the start and end tags, to show
older browser that they do not support this tag.
Note: The <canvas> tag is only a container for graphics, you must use
a script to actually paint graphics.
Note: Some browsers already supports the <canvas> tag, like
Firefox and Opera.
Example
<script type="text/javascript">
function drawCanvas()
{
var canvas=document.getElementById('myCanvas');
var ctx=canvas.getContext('2d');
ctx.fillStyle='#FF0000';
ctx.fillRect(0,0,80,100);
}
</script>
...
<canvas id="myCanvas">your browser does
not support the canvas tag </canvas>
