Q. What is “flush-and-hang style”?
A. The normal style for paragraphs indents the first line only. Flush-and-hang style does not indent the first line (and thus the line remains “flush left”), but it does indent all the rest of the lines (“hanging” them). This style is often used for numbered or bulleted lists. You can find more information about flush-and-hang style by looking in the index at the CMOS Online site under F. Or type “flush hang” into the Search box.
