Punctuation two styles differ mainly in the way in which they handle quotation marks, particularly in conjunction with other punctuation marks. In British English, punctuation such as periods and commas are placed outside the closing quotation mark; in American English, however, punctuation is placed inside the closing quotation mark.

The "question comma" has a comma instead of the dot at the bottom of a question mark, while the "exclamation comma" has a comma in place of the point at the bottom of an exclamation mark. These were intended for use as question and exclamation marks within a sentence, a function for which normal question and exclamation marks can also be used, but which may be considered obsolescent.
