<blockquote>: The Block Quotation element
<blockquote> HTML 元素表示所包含的文本是扩展引用。通常，这是通过缩进在视觉上呈现的（有关如何更改它的信息，请参阅 注意）。引用来源的 URL 可以使用 cite 属性给出，而来源的文本表示可以使用 <cite> 元素给出。
¥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.

示例
¥Examples
此示例演示如何使用 <blockquote> 元素引用 RFC 1149（鸟类载体上 IP 数据报传输标准）中的一段话。
¥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.
