In HTML and XHTML, the blockquote element defines a block quotation within the text. The syntax is <blockquote>blockquoted text goes here</blockquote>.
The blockquote element is used to indicate the quotation of a large section of text from another source. Using the default HTML styling of most web browsers, it will indent the right and left margins both on the display and in printed form.
The excerpt above uses the blackquote tag and is an example of how it can be styled.
