1. History, Vision & Future of HTML5 1.3 Future of HTML5 84% of Developers Plan to Adopt Key HTML5 Features The key to understanding HTML5 is that it is not one, but a group of technologies. Within HTML5, developers have a tremendous amount of choice regarding what they use and what they don’t use The power of HTML5 being ready for prime-time can be seen in Microsoft’s choice to utilize it in Windows 8 Still on the fence with adopting HTML5 in your next project?

2. Getting started with HTML5 Wondering what it takes to get it started? Any Text editor such as Notepad++, Editplus, Textmate, Dream weaver Modern browsers such as Firefox 3.5 +, IE9, chrome, safari Prior knowledge of HTML 4

3. Structure of Web page 3.1. New and Updated HTML5 Elements HTML5 introduces 28 new elements:,,,,,,,,,,,,,,,,,,,,,,,,,, and An HTML page first starts with the DOCTYPE declaration HTML5 also update some of the previous existing elements to better reflect how they are used on the Web or to make them more useful such as: The element can now also contain flow content instead of just phrasing content The element is now representing a paragraph-level thematic break The element only represent the title of a work The element is now representing importance rather than strong emphasis

Basically, it is used to bring the reader's attention to a part of the text that might not have been

3. Structure of Web page 3.3. New Semantic Elements : The tag specifies self-contained content, like illustrations, diagrams, photos, code listings, etc. While the content of the element is related to the main flow, its position is independent of the main flow, and if removed it should not affect the flow of the document

3. Structure of Web page 3.3. Designing blog with html5 IE layout There’s one gotcha about styling HTML 5 pages in IE: it doesn’t work. You can force it to quite easily with a JavaScript hack document.createElement('element name'). HTML 5 enabling scriptHTML 5 enabling script which I use in the header to conjure all the missing elements into existence all at once.

3. Structure of Web page 3.3. why so much fuss for semantics in html5 Well, they add semantics to the page. The browser now knows which area of your site is the header or the footer because there are header and footer elements, whereas div might be called “branding The first is for search engine use; it’s easy to imagine Messrs Google or Yahoo! giving lower weighting to content in footer elements, or extra weight to content in the header. site navigable for people with disabilities.
