<p>
  According to the
  <a href="/en-US/docs/Web/HTML/Element/blockquote">
    <cite>MDN blockquote page</cite></a>:
</p>

<blockquote
  cite="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/blockquote">
  <p>
    The <strong>HTML <code>&lt;blockquote&gt;</code> Element</strong> (or
    <em>HTML Block Quotation Element</em>) indicates that the enclosed text is
    an extended quotation.
  </p>
</blockquote>

<p>
  The quote element — <code>&lt;q&gt;</code> — is
  <q cite="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/q">
    intended for short quotations that don't require paragraph breaks.
  </q>

  documents.

Marking up contact details​

<address> <br /> the line break element

<address>
  <p>
    Chris Mills<br />
    Manchester<br />
    The Grim North<br />
    UK
  </p>

  <ul>
    <li>Tel: 01234 567 890</li>
    <li>Email: me@grim-north.co.uk</li>
  </ul>
</address>

Note: The <address> element should only be used to provide contact information for the document contained with the nearest <article> or <body> element. It would be correct to use it in the footer of a site to include the contact information of the entire site, or inside an article for the contact details of the author, but not to mark up a list of addresses unrelated to the content of that page.

Superscript and subscript​

<sup> <sub>

  <code>&lt;center&gt;</code>.
