Web developers pretty much think this way, since we’re always hearing about something new. A year ago HTML5 and CSS3 seemed so far off in the distance, but already companies are using these technologies in their work today because browsers like Google Chrome, Safari, Firefox, and Opera are starting to implement pieces of the specification.
HTML5 and CSS3 help lay the groundwork for the next generation of web applications. They let us build sites that are simpler to develop, easier to maintain, and more user-friendly. HTML5 has new elements for defining site structure and embedding content, which means we don’t have to resort to extra markup or plug-ins.
Improved accessibility support will improve Ajax applications for people with disabilities, and offline support lets us start building working applications that don’t need an Internet connection. In this book, you’re going to find out about all of the ways you can use HTML5 and CSS3 right now, even if your users don’t have browsers that can support all of these features yet.
