This plugin offers an option to wrap initial quotes in a span of class
dquo. You can then style these classes in your CSS stylesheet. This is useful if you want to-for example-negatively indent quotes so the quote hangs in the left margin and the text is aligned with the text below.
Please note, this applies only to initial quotes — quotemarks that appear as the first character of a block of text (like a paragraph or blockquote). This does not apply to all opening quotes.
