The <br> element introduces the line break. This means that without this tag, your paragraph will retain its behavior and display text on a single line. The most common uses of this tag are seen in written poems and addresses. Keep in mind that the <br> tag is an empty one, so you don't have to worry if you closed it. It's also an inline element that isn't as greedy as block-level elements, so it only takes up as much width as necessary.
