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, but this may be overridden by Cascading Style Sheets (CSS)

<q> elements is
cite= where the provenance of the material quoted may be given. If the quotation is in a language other than that of the main document,
lang= and maybe
dir= attributes may be relevant to specify the language of the quoted text and perhaps its direction, left-to-right or right-to-left.
class= may be used for semantic or styling purposes.
