One of the goals of HTML5 is to make the web completely independent of plugins such as Silverlight, Flash or java applets. To handle this HTML5 introduced the canvas API to create own graphics in our websites with help of JavaScript. It creates a drawing surface a blank area with in the browser that area is marked of in XY coordinates. In this tutorial i want to explain how to create different shapes using canvas element easily with examples. Lets Start with rectangles

    var edge = 20;
    context.fillStyle = "rgba(0, 0, 255, 0.25)";
 //Another way to define fill style
 //context.fillStyle = "grey";
    context.fillRect(20, 20, 260, 110);
