4.5.4 The blockquote element

Categories
Flow content.
Sectioning root.
formatBlock candidate.
Contexts in which this element can be used:
Where flow content is expected.
Content model:
Flow content.
Content attributes:
Global attributes
cite
DOM interface:
interface HTMLQuoteElement : HTMLElement {
           attribute DOMString cite;
};

The HTMLQuoteElement interface is also used by the q element.

The blockquote element represents a section that is quoted from another source.

Content inside a blockquote must be quoted from another source, whose address, if it has one, may be cited in the cite attribute.

If the cite attribute is present, it must be a valid URL potentially surrounded by spaces.

The cite IDL attribute must reflect the element's cite content attribute.

This next example shows the use of cite alongside blockquote:

<p>His next piece was the aptly named <cite>Sonnet 130</cite>:</p>
<blockquote cite="http://quotes.example.org/s/sonnet130.html">
  <p>My mistress' eyes are nothing like the sun,<br>
  Coral is far more red, than her lips red,<br>
  ...

This example shows how a forum post could use blockquote to show what post a user is replying to. The article element is used for each post, to mark up the threading.

<article>

This example shows the use of a blockquote for short snippets, demonstrating that one does not have to use p elements inside blockquote elements:

<p>He began his list of "lessons" with the following:</p>
<blockquote>One should never assume that his side of 
the issue will be recognized, let alone that it will 
be conceded to have merits.</blockquote>
<p>He continued with a number of similar points, ending with:</p>
<blockquote>Finally, one should be prepared for the threat 
of breakdown in negotiations at any given moment and not 
be cowed by the possiblity.</blockquote>
<p>We shall now discuss these points...

Examples of how to represent a conversation are shown in a later section; it is not appropriate to use the cite and blockquote elements for this purpose.
