HTML is fast, secure, responsive, interactive, and stunningly beautiful. It lets you target the largest number of devices and browsers with the least amount of effort. Working with the latest technologies is always fun and with a rapidly growing mobile market, it is a new and exciting place to be."Learn HTML5 by Creating Fun Games" takes you through the journey of learning HTML5 right from setting up the environment to creating fully-functional games. It will help you explore the basics while you work through the whole book with the completion of each game."Learn HTML5 by Creating Fun Games" takes a very friendly approach to teaching fun, silly games for the purpose of giving you a thorough grounding in HTML5. The book has only as much theory as it has to, often in tip boxes, with most of the information explaining how to create HTML5 canvas games. You will be assisted with lots of simple steps with screenshots building towards silly but addictive games.The book introduces you to HTML5 by helping you understand the setup and the underlying environment. As you start building your first game that is a typography game, you understand the significance of elements used in game development such as input types, web forms, and so on.We will see how to write a modern browser-compatible code while creating a basic Jelly Wobbling Game. Each game introduces you to an advanced topic such as vector graphics, native audio manipulation, and dragging-and-dropping. In the later section of the book, you will see yourself developing the famous snake game using requestAnimationFrame along with the canvas API, and enhancing it further with web messaging, web storage, and local storage.

This format may seem complicated enough to be confused with a full blown programming language for 2D graphics, but in truth it is just a markup language. While SVG may seem new to some web developers, the specification was first developed back in 1999.

The main difference between a vector graphic and a raster graphic (in other words, a bitmap) is the way that the graphic is described. In a bitmap, each pixel is essentially represented by three or four numbers, representing the color of that individual pixel (RGB), along with a possible opacity level. Looking at it from a broader sense, a bitmap is nothing more than a grid of pixels. Vectors, on the other hand, are described by a series of mathematical functions that describe lines, shapes, and colors, instead of each individual point on the entire image. To put it in simple terms, vector graphics do a fantastic job of scaling its dimensions, as...
