Overview of this book

HTML5's new features have made it a real application development platform with widespread adoption throughout the industry for this purpose. Being able to create one application that can run on virtually any device from phone to desktop has made it the first choice among developers. Although JavaScript has been around for a while now, it wasn't until the introduction of HTML5 that we have been able to create dynamic, feature-rich applications rivaling those written for the desktop. HTML5 Web Application Development By Example will give you the knowledge you need to build rich, interactive web applications from the ground up, incorporating the most popular HTML5 and CSS3 features available right now. This book is full of tips, tools, and example applications that will get you started writing your own applications today. HTML5 Web Application Development By Example shows you how to write web applications using the most popular HTML5 and CSS3 features. This book is a practical, hands-on guide with numerous real-world and relevant examples. You will learn how to use local storage to save an application's state and incorporate CSS3 to make it look great. You will also learn how to use custom data attributes to implement data binding. We'll use the new Canvas API to create a drawing application, then use the Audio API to create a virtual piano, before turning it all into a game. The time to start using HTML5 is now.

transform: function();

There are a few different 2D transform functions. The first we'll look at is translate(). It moves an element from its current position to a new position. It takes x and y positions as parameters. You can use negative values to move up and to the left. The following would move an element 10 pixels right and 25 pixels up:

transform: translate(10px, -25px);

The rotate() function rotates an element by a given amount. The rotation amount can be specified in degrees or radians. Use negative values to rotate counter clockwise, positive for clockwise:

transform: rotate(45deg);

The scale() function adjusts the size of an element by some factor. It takes one or two parameters. If only one...
