It’s important to note, however, that not all punctuation automatically goes inside the quotation marks. Question marks are a little trickier. If the only part in quotations is a question, then the question mark should go inside the quotation marks; otherwise, the question mark actually goes outside of the quotation marks. Tricky for sure!
Also, beginning writers often forget that titles of shorter works, like essays and short stories, should be placed inside quotation marks. Longer works, like books and magazines, should be placed in italics.
