HTML and CSS Reference
<p> The new HTML5 specification is in the works. While many features are
not currently implemented or even well defined yet, progress is being made.
Stay tuned to see more new HTML elements added to your Web documents in the
years to come. </p>

HTML5 Not currently supported by any browser, but can be addressed with a custom element.
• Early versions of this tag supported pubdate and cite attributes but these were
removed later in favor of nested <time> tags.
• It is possible to nest <article> tags and the relationship should logically relate to
the parent <article> subject matter.
• This element is not directly implemented in any browser. However, given that most
browsers can handle custom elements, it is easy enough to simulate the idea of it
and even apply a CSS display property for it.
This HTML5 element defines a section of a document that encloses content that is
tangentially related to the other content the element may be associated with. A simple
example of this element in action might be to specify sidebar content.
