Html 5: The Article Contents element

The HTML <article> element represents a self-contained composition in a document, page, application, or site, which is intended to be independently distributable or reusable (e.g., in syndication). Examples include: a forum post, a magazine or newspaper article, or a blog entry.

• Each <article> should be identified, typically by including a heading (<h1>-<h6> element) as a child of the <article> element.
• When an <article> element is nested, the inner element represents an article related to the outer element. For example, the comments of a blog post can be <article> elements nested in the <article> representing the blog post.
• Author information of an <article> element can be provided through the <address> element, but it doesn't apply to nested <article> elements.
• The publication date and time of an <article> element can be described using the datetime attribute of a <time> element. Note that the pubdate attribute of <time> is no longer a part of the W3C HTML5 standard.
