Chapter 2 and Appendix A will teach you how to properly detect support for each new HTML5 feature.
Now, if you want to improve your web applications, you’ve come to the right place. Here’s a concrete example: HTML5 supports all the form controls from HTML 4, but it also includes new input controls. Some of these are long-overdue additions like sliders and date pickers; others are more subtle. For example, the email input type looks just like a text box, but mobile browsers will customize their onscreen keyboard to make it easier to type email addresses. Older browsers that don’t support the email input type will treat it as a regular text field, and the form still works with no markup changes or scripting hacks. This means you can start improving your web forms today, even if some of your visitors are stuck on IE 6.
3. It’s easy to get started. “Upgrading” to HTML5 can be as simple as changing your doctype. The doctype should already be on the first line of every HTML page. Previous versions of HTML defined a lot of doctypes, and choosing the right one could be tricky. In HTML5, there is only one doctype: !DOCTYPE html
Upgrading to the HTML5 doctype won’t break your existing markup, because all the tags defined in HTML 4 are still supported in HTML5. But it will allow you to use -- and validate -- new semantic elements like article, section, header, and footer. You’ll learn all about these new elements in Chapter 3.
- Today the Director announces that when the XHTML 2 Working Group charter expires as scheduled at the end of 2009, the charter will not be renewed. By doing so, and by increasing resources in the HTML Working Group, W3C hopes to accelerate the progress of HTML5 and clarify W3C’s position regarding the future of HTML.
