The <blockquote> tag defines a long quotation like paragraphs (instead of HTML q tag used for in-line content). A browser inserts white space before and after a blockquote element. It also inserts margins for the blockquote element. The HTML blockquote element begins with the HTML <blockquote> tag and ends with the HTML </blockquote> tag.
Syntax:
<blockquote cite="http://www.c-sharpcorner.com/">
Cite - This is a optional attribute which can be used to specify the location (in the form of a URI) where the quote has come from.
Attributes
HTML tags can contain one or more attributes. Attributes are added to a tag to provide the browser with more information about how the tag should appear or behave. Attributes consist of a name and a value separated by an equals (=) sign, with the value surrounded by double quotes.
There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes.
