Explain about abbr and address element.

The HTML <abbr> element defines an abbreviation or an acronym.
Marking abbreviations can give useful information to browsers, translation systems and search-engines.

Example

<p>The <abbr title="United Nations">UNO</abbr> was founded in 1945.</p>

 

 

The HTML <address> element defines contact information (author/owner) of a document or an article.
The <address> element is usually displayed in italic. Most browsers will add a line break before and after the element.
