Don’t Fear the Internet Five Things You Should Know About HTML5 You are here: Home Dive Into HTML5 1. It’s not one big thing You may well ask: “How can I start using HTML5 if older browsers don’t support it?” You may think of HTML as tags and angle brackets. Chapter 2 and Appendix A will teach you how to properly detect support for each new HTML5 feature. 2. Love it or hate it, you can’t deny that HTML 4 is the most successful markup format ever. Now, if you want to improve your web applications, you’ve come to the right place. Read all the gory details about HTML5 forms in Chapter 9. 3. “Upgrading” to HTML5 can be as simple as changing your doctype. Upgrading to the HTML5 doctype won’t break your existing markup, because obsolete elements previously defined in HTML 4 will still render in HTML5. 4. Whether you want to draw on a canvas, play video, design better forms, or build web applications that work offline, you’ll find that HTML5 is already well-supported. Each chapter of this book includes the all-too-familiar browser compatibility charts. 5.

HTML DOM Document Objects Video Subtitling and WebVTT We’ve been able to play video in the browser without a plugin for a couple of years now, and whilst there are still some codec annoyances, things appear to have settled down on the video front. The next step is adding resources to the video to make it more accessible and provide more options to the viewer. We currently have no means to provide information about what’s happening or being said in the video, which means the video isn’t very accessible and the user can’t easily navigate to a particular section of the video. Thankfully, there’s a new format specification in the works called WebVTT (Web Video Text Tracks). As of now, it’s only in the WHATWG spec, but the recently established W3C Web Media Text Tracks Community Group should introduce a WebVTT spec to the W3C soon. You may recall a similar format called WebSRT (Web Subtitle Resource Tracks) that was recently under discussion. A WebVTT (.vtt) file is simply plain text containing several types of information about the video: Demo #

The article tag - Complete HTML5 tutorial The article element is one of the new elements that have been introduced with HTML5. As this is a new element there has been some confusion of how to use this element. But there seems to be an agreement that you use the <article> element when you markup content, that makes sense on its own. Using the Flour-article, the article element should be used like this (please note, that I have replaced a lot of the actual content with three dots, so that the example does not take up too much space): <! As you can see, the <article> element contains the <div id="header"> and the <div id="content"> as the content in these two <div>’s can be read as a whole article.
