Component used to distinguish quoted text in a document by increasing the size of the quote, giving it an attribution, and adding a border around it. For those interested, there's a slight difference between block and pull quotes:
A block quotation (also known as a long quotation or extract) is a quotation in a written document that is set off from the main text as a paragraph, or block of text, and typically distinguished visually using indentation and a different typeface or smaller size font.
Subtext under the quote. Generally the name of the person who said the quote.
