But more than the actual demonstration itself, what I hope to have imparted here is the motivation to explore the Canvas API to see if you can push your limits and be on the cutting edge. This bouncing ball is a fundamental concept to many of the game development logic and it can be easily extended to build a ping-pong game or a breaker-type of game. If all goes well, you should see a ball bouncing around the four corners of the canvas element (like in the demo).

Note that it’s better to write unobtrusive JavaScript but I would like to keep this exploration brief, simple and as self-explanatory in code as possible. Then when the HTML document is loaded (body’s onLoad), we just call the init() function. Basically, we define the context, initiate the drawing, then we use color and style methods to fill in the color and dictate the shape (using a Math object for a circle). The syntax is self-explanatory, especially if you’re familiar with JavaScript. We are going to draw a circle using the arc and fill methods. Now let us start with the actual work of creating our shapes in JavaScript. I also defined the element’s dimensions (width/height), however, you could just as well do that via CSS by targeting the #m圜anvas ID. Though we only have one element in our HTML for this example, I have still assigned an ID to it ( m圜anvas) just to make it easier/quicker to select it later on via JavaScript. It’s best if you follow along with me as we go - so go ahead and create your HTML document now. To start, you will need to create a basic HTML document. CSS doesn’t play a part in the appearance and functionality of the bouncing ball, so we don’t need to discuss it. Note that we will skip CSS because this guide is about HTML5 and JavaScript.
So that we may explore the element through a hands-on approach, we will create a ball that will be bouncing around using HTML5 specifications and JavaScript.

While in HTML merely allows you to define a region in terms of width and height, everything else related to the actual drawing of the shapes is done through JavaScript via a full set of drawing functions and methods (collectively known as the Canvas 2D API).
Practical uses for this are things such as dynamic charts that are populated by data from a relational database like MySQL or web games that rely solely on open technologies (JavaScript/HTML). The tag primarily allows you to render 2D shapes and images dynamically using math functions.

View Demo Download Source An Overview of HTML5’s Canvas This guide will explore the use of HTML5’s element through a fun example: bouncing a blue ball around. It is widely supported by popular browsers like Firefox, Chrome, Safari and Opera (Internet Explorer supports it in their IE9 beta version). As many of you right now, the element is one of the most popular additions to the HTML5 standards.
