Remember the canvas element? Below is an example.
<html>
<head>
<title>Canvas</title>
<style>
#myCanvas{
border:black;
border-style: solid;
border-width: 2px;
}
</style>
</head>
<body>
<canvas id="myCanvas" height="600" width="800"></canvas>
</body>
</html>
Now, try working on not only creating the canvas but making sure you can draw something to this canvas like a square or some other shape or image.
