Question mark inside or outside quotes refers to the placement of question marks in relation to quotation marks in written text. There are two main styles for this: American style and British style.
American style places the question mark inside the quotation marks if the question is part of the quoted material. For example:
She asked, “Are you coming?”
If the question is not part of the quoted material, the question mark is placed outside the quotation marks. For example:
Did she ask, “Are you coming?”
