دانلود کتاب راهنمای ضروری HTML5 – استفاده از بازی برای یادگیری HTML5 و جاوا اسکریپت

When it was first released, there was considerable enthusiasm about the new capabilities of HTML5, and even suggestions that no other technologies or products are necessary to produce dynamic, engrossing, interactive websites. The excitement has not gone away, and the new features are still exciting. HTML is HTML5. It now is possible, using just HTML, Cascading Style Sheets, and JavaScript, to draw lines, arcs, circles, and ovals on the screen and specify events and event handling to produce animation and respond to user actions. You can include video and audio on your website with standard controls, and you can include the video or audio in your application exactly when and where needed. You can create forms that validate the input and provide immediate feedback to users. You can use a facility similar to cookies to store information on the client computer. And you can use new elements, such as headers and footers, to help structure your documents. HTML, CSS, and JavaScript work together. You can use JavaScript to create new HTML elements, and this is helped by what can be done with CSS. This book is based on my teaching practices and past writings. Delving into the features of a technology or general programming concepts is best done when there is a need and a context. Games, especially familiar and simple ones, supply the context and thus the motivation and much of the explanation. When learning a new programming language, one of my first steps is to program the game of craps. Also, if I can build a ballistics simulation with animation, such as the slingshot game, and make a video or audio clip play when a specific condition occurs, I am happy. If I can construct my own maze of walls, determine ways to provide visual as well as text feedback, and store information on the player’s computer, I am ecstatic. That’s what we will do in this book. As you learn how to build these simple games, you’ll build your expertise as well. I hope you go on to make your own exciting, compelling applications. This goal of this book, developed with considerable help from the Apress staff and the technical reviewers, is to introduce you to programming, with the motivation of implementing interactive websites to share with others.
