This property determines the type of quotation marks that will be used in a document. One or more quotation mark pairs are given, with the basic quotation characters being the left-most pair. Each subsequent pair represents the quotation characters used at progressively deeper element nesting contexts.
Values of the ‘content’ property are used to specify where the open/close quotation marks should or should not occur - the “open-quote”, “close-quote”, “no-open-quote”, and “no-close-quote” values. “Open-quote” refers to the left (first) of a given pair of specified quotes, while “close-quote” refers to the second (right) quote character in the pair. Quotes can be skipped at a particular location by using the “no-close-quote” and “no-open-quote” value. In the event that the quote character nesting depth is not covered in the ‘quotes’ property specification, the last valid quotation pair set should be used.

blockquote[lang-=fr] { quotes: “\201C” “\201D” }

blockquote[lang-=en] { quotes: “\00AB” “\00BB” }

blockquote:before { content: open-quote }

blockquote:after { content: close-quote }
