And to use it it's

<div class="block letter"><p>blah</p><p>blah</p></div>

As a side note I don't understand (or have forgotten) why the div.article doesn't need the space p while the div.letter does. E.g., if you do

<div class="article block">First article sentence.</div>
<div class="letter block">First letter sentence.</div>

The article sentence is sans serif but the letter sentence is not italic.

The letter sentence requires a p tag for the "div.letter p" to apply -- it applies to p elements inside a div element.
