The <blockquote> HTML element indicates that the enclosed text is an extended quotation. Usually, this is rendered visually by indentation (see Notes for how to change it). A URL for the source of the quotation may be given using the cite attribute, while a text representation of the source can be given using the <cite> element.

This element's attributes include the global attributes.

cite

A URL that designates a source document or message for the information quoted. This attribute is intended to point to information explaining the context or the reference for the quote.

To change the indentation applied to the quoted text, use the CSS margin-left and/or margin-right properties, or the margin shorthand property.

To include shorter quotes inline rather than in a separate block, use the <q> (Quotation) element.

This example demonstrates the use of the <blockquote> element to quote a passage from RFC 1149, A Standard for the Transmission of IP Datagrams on Avian Carriers.

<blockquote cite="https://datatracker.ietf.org/doc/html/rfc1149">
  <p>
    Avian carriers can provide high delay, low throughput, and low altitude
    service. The connection topology is limited to a single point-to-point path
    for each carrier, used with standard carriers, but many carriers can be used
    without significant interference with each other, outside early spring. This
    is because of the 3D ether space available to the carriers, in contrast to
    the 1D ether used by IEEE802.3. The carriers have an intrinsic collision
    avoidance system, which increases availability.
  </p>

• The <q> element for inline quotations.
• The <cite> element for source citations.
