Head First HTML5 Programming

Building Web Apps with JavaScript

• Broschiertes Buch

Produktbeschreibung

HTML has been on a wild ride. Sure, HTML started as a mere markup language, but more recently HTML’s put on some major muscle. Now we’ve got a language tuned for building web applications with Web storage, 2D drawing, offline support, sockets and threads, and more. And to speak this language you’ve got to go beyond HTML5 markup and into the world of the DOM, events, and JavaScript APIs. Head First HTML5 Programming is your ultimate tour guide to creating web applications with HTML5 and JavaScript, and we give you everything you need to know to build them, including: how to add interactivity to your pages, how to communicate with the world of Web services, and how to use the great new APIs being developed for HTML5.

What can HTML5 do for you? If you're a web developer looking to use this new version of HTML, you might be wondering how much has really changed. Head First HTML5 introduces the key features -- including improved text elements, audio and video tags, geolocation, and the Canvas drawing surface -- and uses concrete examples and exercises to apply and reinforce these concepts. You'll learn how HTML5, Javascript, and CSS3 will help create fast, interactive sites with fewer plugins. Get the low-down on changes to the basic HTML markup Explore CSS3, and discover how it compliments HTML5 Understand JavaScript's relationship to HTML5 Learn HTML5's new font, multicolumn, and text capabilities Bring out your inner artist with Canvas Use the technology to add audio and video Take advantage of local storage and databases Learn how HTML5 deals with geolocation, multitouch, and more We think your time is too valuable to waste struggling with new concepts. Using the latest research in cognitive science and learning theory to craft a multi-sensory learning experience, Head First HTML5 uses a visually rich format designed for the way your brain works, not a text-heavy approach that puts you to sleep.
