Occasionally, you will want to manually break a line without ending the paragraph.
For example, consider the example

Since the text is from a play, it follows a particular style:
Actor-name
Dialogue

If you use a paragraph tag to cause each line break, you’ll end up with output similar
to the following:

Fran.
You come most carefully upon your hour.
Ber.
‘Tis now struck twelve. Get thee to bed, Francisco.
Fran.
For this relief much thanks: ‘tis bitter cold,
And I am sick at heart.

Instead, you should use a line break tag (<br>) where you need a line break in a
paragraph.
 The preceding text would be coded as follows:

 NOTE:Typically, you would use several different styles of paragraph tags to delimit the
different elements.
For example, when formatting a script for a play, you would
have a class for the actor and another for the dialogue.
An example follow:

That way, you could easily control (and change) the format of each element
separately.
