One of the consequences of using <br/> is that first-line indent will no longer work. It has its uses, though. For instance, in short fragment of centered text, or in titles:
Code:
<h2>Chapter 1<br/>An Unexpected Party</h2>
Code:
<div class="center">
Alphonse Allais<br/>
FABRICANT D’ÉCRABOUILLITE
</div>
