HTML: address Tag

The address tag is for contact info of the article author or page's owner.

<address>
Contact <a href="http://example.com/author.html">Joe Lee</a>.
</address>

The address tag can contain author email or author street address. For example:

<address>
Write to Joe at <a href="mailto:joe@example.com">joe@example.com</a>.
</address>

The main thing is that it marks up a contact info of the article. There's no strict structure of what content inside “address” tag should be. Also, the “address” tag is often conveniently placed inside “header” or “footer” tags. [see HTML5 Page Article Tag and Page Structure Tags]

Warning: the “address” tag should NOT be used for arbitrary address that has nothing to do with the author or page owner.
