HTML normally answers the question of whether white space is
significant or not by predefining the meaning of white space in
particular elements. For instance, white space is significant
inside <pre> and </pre> tags.
It's not significant almost everywhere else. This means that if
you want to preserve line breaks without using a monospaced
font, you need to insert a lot of <br> tags as
in this first stanza from William Blake's poem The
Tyger:
Tyger! Tyger! burning bright
In the forests of the night
What immortal hand or eye
Could frame thy fearful symmetry?
