Nos encontramos al final de una revolución. La Web se está convirtiendo en la principal plataforma de desarrollo y en la fuente principal de información y recursos. En los últimos años los dispositivos móviles han convertido las aplicaciones de Internet en una necesidad. Día a día surgen nuevos y más sofisticados programas para la Web, reemplazando, de forma muy efectiva, a las aplicaciones tradicionales de escritorio. Este nivel de cambio es, a la vez, radical y experimental, y HTML5 lo está haciendo posible.
El gran libro de HTML5, CSS3 y Javascript guía al lector paso a paso en la adquisición de los conocimientos básicos y el dominio de los temas más complejos incluidos en la especificación de HTML5. Después de leer este libro usted sabrá cómo estructurar sus documentos con HTML5, cómo aplicar estilos utilizando CSS3 y cómo trabajar con las más poderosas APIs de Javascript.
Este libro no es una introducción a HTML5 sino un curso completo que le enseñará cómo construir sitios Web profesionales y aplicaciones Web extraordinarias desde cero. Cada capítulo explora conceptos básicos, así como complicados, sobre HTML5, CSS3 y Javascript. Los conceptos vertidos son soportados por códigos completamente funcionales que guían, al iniciado y al experto, a través de cada etiqueta, estilo o función incluida en esta especificación. Los códigos aparecen distribuidos a lo largo del libro en un orden específico que gradualmente introduce conceptos complejos y los hace realmente accesibles.
Este libro abarca: API Canvas, API Drag and Drop, API Geolocation, API Web Storage, API IndexedDB, API File, API Communication, API Web Workers, API History, API Offline, API Forms, API Media, los nuevos elementos HTML, el modelo de caja tradicional, el elemento video, el elemento audio, los nuevos elementos para formularios, validación de formularios, los nuevos selectores CSS, las nuevas pseudo clases, sombras, fuentes, colores, gradientes, translación, transformación, los nuevos selectores Javascript, los nuevos estándares, las librerías externas y más.
We know from the success of titles such as Web Standards Solutions, Cascading Style Sheets: Separating Content from Presentation, and TheWeb Designer's Reference that web designers are increasingly concerned with making sites that don’t just look pretty, but are also built using current best practices.
There are three main technologies married together to create usable, standards-compliant web designs: XHTML for data structure, Cascading Style Sheets for styling your data, and JavaScript for adding dynamic effects and manipulating structure on the fly using the Document Object Model.
This book is about the latter of the three. DOM Scripting: Web Design with JavaScript and the Document Object Model gives you everything you need to start using JavaScript and the Document Object Model to enhance your web pages with client-side dynamic effects. Jeremy Keith starts off by giving you a basic crash course in JavaScript and the DOM, then moves on to provide you with several real-world examples built up from scratch, including dynamic image galleries and dynamic menus. Then, he shows you how to manipulate web page style using the CSS DOM, and create markup on the fly.

Question : How to fix javascript errors in my windows vista computer?
My pc has javascript error message pops up. My OS is vista. Can u kindly tell me how to fix in in plain English?
Answer:
There are mainly two reasons:1. If you are getting JavaScript error when using a certain program then you can try to update the program and check if the problem is solved, or u can reinstall the program.2. If you are experiencing errors from webpage you can check if Active script, Java applets, or ActiveX is blocked on your browser settings. Check other computer if they are getting Javascript error when opening that website. If yes then the problem lays on the website itself, not your computer.If none of these solutions work, then you have a problem in your system files or registry. Registry cleaner program will scan all errors in your computer and repair them. They will eliminate all possible causes of bugs and errors. Registry easy is the best cleaner among those cleaner. U can easily fix all errors in ur pc like a pc guru:)

Question : How can I call a Javascript event on a HTML div border corners?
It sounds confusing, but is quite simple. I have a square div, and using css I have four circles replacing the corners of the of the divs border. I want the user to be able to click on one of the corner circles changing the curser image and calling the Javascript onclick event. How do I did that?
Answer:
The corners of the div are not in themselves elements that you can give attributes to (other than the border color and width). But do simulate this you can easily making a div superimposed on a larger div, thus making it seem as if the back div is it's border.
