Doctype is now a simple <!DOCTYPE html>
Common structural divs are now their own tags.
Here are the self explanatory ones:
<div id=”header”> is now <header>
<div id=”nav”> is now <nav>
<div id=”footer”> is now <footer>
Tags that need a little clarification:
According the HTML 5 spec, a section is a thematic grouping of content, typically preceded cheap cialis by a header tag, and followed by a footer tag. But sections can also be nested inside of each other, if needed.
WHATWG notes, the article element should wrap “a section of content that forms an independent part of a document or site; for example, a magazine or newspaper article, or a blog entry.”
You can have more than one article tag on a page and each article can also be broken into sections using a section tag. This is very similar to how CMS systems like Joomla specify content but be careful when planning you structure in HTML 5 so as not to create a tag sea.
Text in parentheses, annotations, pull quotes, inline footnotes or sidebar content would all fall under this tag.
