Basically I think <em> is by default tied to italic by tradition in
print, but of course you can always change this to something more to
your liking in your stylesheet

Depends if you are just highlighting a specific word or phrase then 'em'
and 'strong' will do but if there is some underlining theme to the
emphasis then I could see where classes can be very useful, e.g.
..keyword { color: #080; }
..constant { color: #f00; }
..command { color: #008; }
<span class="keyword">void</span>
<span class="constant">NULL</span>
<span class="command">sub</span>
which gives you the flexibility if latter you rethink the color coding a
bit garish then all you have to do is change your stylesheet...
..keyword, .constant, .command { color: #f00; font-weight: bold; }
