Draw With Javascript

The canvas element has no drawing abilities of its own. All drawing must be done inside a JavaScript:

JavaScript uses the id to find the canvas element:

var c=document.getElementById("myCanvas");

Then, create a context object:

var cxt=c.getContext("2d");

The getContext("2d") object is a built-in HTML5 object, with many methods to draw paths, boxes, circles, characters, images and more.

The next two lines draws a red rectangle:

cxt.fillStyle="#FF0000";
cxt.fillRect(0,0,150,75);

The fillStyle method makes it red, and the fillRect method specifies the shape, position, and size.
