The <address> tag in HTML is used to define contact information related to the author or owner of a document, article, or a specific section of content. Typically, it contains details like physical addresses, email addresses, phone numbers, or links to social media profiles.

Syntax:

<address>
  Contact Information
</address>

Usage and Context:

• The <address> tag is intended for contact details only, not for representing a geographical address on its own.
• It is commonly used in the footer of a webpage or alongside an article to provide information about the content creator or organization.

Example:

<address>
  Written by <a href="mailto:someone@example.com">John Doe</a>.<br>
  Visit us at:<br>
  Example Inc.<br>
  1234 Main St.<br>
  Anytown, USA
</address>

In this example:

• The <address> tag wraps contact information, including an email link, company name, and physical address.
• The contact information appears formatted with line breaks for clarity.

Display:

The <address> tag typically renders the content in italic by default in most browsers and applies block-level formatting, meaning it starts on a new line and spans the full width available.

Use Cases:

1. Author's Contact Information: If a webpage or an article needs to show who authored the content and how to contact them.
2. Company Information: Businesses can display their contact information, including address, email, and phone numbers.
3. Footer Section: It is often used in the footer of a website to display the website owner's contact details.

Example for Footer:

<footer>
  <address>
    Contact us at <a href="mailto:info@example.com">info@example.com</a>.<br>
    1234 Example Ave, Suite 100<br>
    City, Country 56789
  </address>
</footer>

Misuse Warning:

The <address> tag should only be used for contact information. It is not meant for geographical addresses in a broader context (like a map location) or to display random text.
